I kind of get the whole 'price premium isn't reflected in the additional value' argument, though you could argue similar things about the difference in price between Japanese and recent Chinese imports e.g. the Great Wall X200 for about $20K driveaway looks like an absolute bargain compared to the Forrester.

Regardless of the absolute comparability of the Jeep vs Merc or even the Forrester, I think you did a disservice to the guy that asked the question .. the only prime requirement he gave was "We are not getting any younger and could do with a lower vehicle with easier entry and exit for my sweet little Nana", because in my opinion the Forrester doesn't really meet that requirement, it's still a high riding SUV for the most part. The other aspect of the Jeep he appreciated was "The smooth ride" - clearly full on offroad capability isnt exactly the top priority either. So he doesnt want a high riding position, and he wants something comfortable that's easy for nana to get in and out of.

If Nana gets to sit in the front, there's tons of room, and the back isn't bad at all unless Nana is close to 6 foot tall.

Also if you're going to set yourself up an expert providing an unbiased  comparison based on logic and rational argument its usually a reasonable idea to throw up the pluses and minuses on both sides.

e.g. On the plus side for the GLA.

Much better fuel economy
More comfortable ride thanks to the longer wheel base
better acceleration
better towing capability
max torque at much lower RPM
Better range
It's also marginally wider, though I'm unconvinced that = more comfort.
There's a slew of other features the benz has that the subie doesnt (like the cornering lights), none of which are deal breakers either way for me personally. Having said apart from the adaptive cruise control and the extra speakers,  the stuff like keyless entry is standard equipement on current models, as are all the safety features.

This kind of "doing more with less" is a genuinely admirable piece of engineering, and the things AMG do with what is basically the same powerplant in the A45 and GLA45 is mind-blowing ..

The subie does have a more powerful engine, and a bigger fuel tank,  but that doesn't seem turn into an advantage in the real world in terms of driving outcomes. It is longer though and has more space in the boot, which is either really great, or it doesn't matter. I think some aspects of the interior are much better than the Benz (note to any MB types reading this .. that big area  in the dash with the stupid number of buttons and dials .. that's where you put the integrated touch screen). The standard satnav thing in the benz is OK, but it looks a bit "tacked on" which kind of detracts from the whole premium experience. Another thing that kind of bugs me but kind of doesnt is the extensive use of "ARTICO" across the benz range .. lets call it what it is, its not "man made leather' its Vinyl (ARTIficial COw). Having said that its a damn good upholstery choice for a car, it's just not leather. I'm not sure, but I suspect the leather in the Subie may actually have surrounded something that you can cut up into steaks at some point.

I'm also absolutely convinced the XT, or even the XV (which is more directly comparable to the GLA, odd you didnt use that as your basis of comparison) would be better in offroad conditions, but ,given the VAST majority of people who use 4x4 do it because they cant be bothered messing around with snow chains, or the occasional dirt road to a camping spot, its hardly a consideration. If it is, then get yourself a proper 4x4. For the other 99.9% of the time you're driving a car around town, the GLA is going to be a more enjoyable ride. I've seen a bunch of impressive videos of the GLA handling snowy and icy conditions. I've also seen videos where it got up a steep slippery grass slope after a few goes .. all the while though I kept thinking .. I would have done that first go in the Kluger.

On the "more speakers front", I personally dont give a toss, the road noise in either car is going to kill anything resembling an audiophile experience, and if it's loud enough to drown that out completely, you probably cant hear warning sirens and horns either. I must be getting old, because I'm complaining about the music being too loud.

Also adaptive cruise control, bought it on my golf, played with it twice, it's still in "gimmick" territory for me, just like automated parking assist.

I also completely disagree with you on the DSG front, I've been driving DSG units for a while now, it took me about about a week to adapt to the differences between a dual clutch system and a slushbox, as a result I'd pick a DSG over any other transmission given a choice. Maybe rather than making blanket assertions that DSG's suck, maybe just say "I dont like them", its one of those personal opinion things. Personally every CVT I've ever been in had this whine that would drive me nuts if I had to listen to it every day, maybe you get used to that too, or maybe they've improved.

It's OK to be opinionated and biased, especially on your own platform, but if your going to give someone advice, I reckon you should try to give some decent balanced advice that addresses the question first, and then let rip.

This is great, but long, so If you're interested in how flashpool works I've selected some start and stop times for the most relevant pieces.

1:273:43  of explanation of how NetApp cache based virtual storage tiering works vs traditional auto-tiering approaches, and why it is superior
13:13 - 15:28 - Intro to Flashpool
15:2818:21 – Long kind of rambly discussion about flash pool about random overwrite caching
18:2120:30 – Good technical explanation of read and write caching in flashpool
20:30 –  Discussion around how we track the age of the block in the cache for ageing (interesting but technically deep)
23:20 -23:47  More Discussion about interactions with snapshots and checkpointing to hard disk
23:48 -24:30  Example of cost reductions for the same performance
24:31 - 25:50   - Discussion on how much cache you can add to a system (numbers are now bigger since ONTAP 8.2.1 was released)
25:50 - 27:05  Example of performance improvements for the same expenditure
27:05 - 29:30 - Summary of when to use flashpool vs flashcache.

This video was produced a little under a year ago, and things have progressed, and my personal feeling is that for greenfield implementations following best practices for Clustered Data ONTAP from 8.2.1 onwards, the non disruptive addition of additional capacity, plus larger sizes and the falling price of SSD makes flashpool the default choice for Automated Storage Tiering, with FlashCache reserved for special use cases.

If you've got the time, the section that follows on FlashAccel is also good, and is now even better with recent updates to the software.

I remember reading this a long time ago ... it sets a bar for what "Thought leadership" should look like in the storage industry.
Tape is Dead Disk is Tape Flash is Disk RAM Locality is King. Jim Gray. Microsoft ... 1995 16 Mb NAND flash chips ... Current FLASH disks could do much better

http://kck.st/17BKz3h  ... 3D Robot Turtles ...  some things are just too cool to ignore ... or is that just me ?

But seriously, IMHO the ability think in structured programmatic ways is not just about the new literacy, or the ability to control a technology that is indistinguishable from magic, its about being able to reduce your problems to small manageable chunks, and think a few moves ahead.

Now if someone has some good suggestions for thinking holistically for kids let me know, until then I'm breaking out the easel,  paintbrushes and modelling clay.
Robot Turtles is the the most-backed board game in Kickstarter history. It sneakily teaches programming fundamentals to kids ages 3+.

I suppose that by ensuring that almost every female gamer I know will think that the Vita is targeted to young men with the mental stature of Beavis and Butthead, you've advanced the status of women in gaming by keeping them away from a truly lame platform. Kudos to Sony for advancing the status of women in the gaming community.

'm tired of being lied to. I'm tired of broken election promises. I'm tired of deceptive corporate marketing. I'm tired of the everyday hypocrisy that surrounds me every day. But most of all I'm tired of the lies I tell myself. Things will change, things must change ... I will begin with what I can control, I will start with myself. I will hold myself to a higher standard of honesty and I will encourage others to do the same. I will be less tolerant of dishonesty in others even when it benefits me. The truth is precious and trans-formative, it is time we treated it with the respect it deserves. #BeTrue.

My first Computerworld blog got published today ... http://blogs.computerworld.com/cloud-storage/22895/designing-cloud-storage-ditch-lun-cfbdcw. I'm feeling somewhat chuffed.
I’m always surprised that so many people still want to build their private and public cloud on logical units, served out by Fibre Channel SANs. From my point of view, we should have ditched the LUN years ago: Storage management problems at scale created by the LUN presents some of the toughest IT challenges, and those problems are a direct result of the massive success of virtualization.
