Reasons why users refrain from installing apps

Straight from today's uselab sessions: 3 reasons why users hesitate to install an app:
1.) It might cost money (now or later)
2.) It's probably unsafe to use an app for that - and I put more trust in the web.
3.) I already have too many apps and won't bother to install another one.

While the first two clearly are trust issues that might be overcome by a carefully phrased introduction to the app (depending on the strength of the user's believes) or just the user becoming more accustomed to the new plattform, the last one is a device management problem to which no mobile OS has come up with even a noteworthy solution yet (folders definitely only postpone the problem).

If you are interested in the mobile web and missed last week's Mobilism 2012 have a look at my summary of the conference.
This article is summing up my personal impressions from Mobilism 2012 with a focus on overarching themes and ideas. Disclosure: I am currently working for a German carrier. I will leave out any topics...

The last session of the Google Developer Day 2011 Berlin just ended. As a brief summary these are the key impressions I took from today:

Judging from the keynote, Android and Google+ are the two focus products most strongly promoted by Google at the moment. Of course, the web (with Chrome Browser and HTML5) ist still an important topic, too. The now released in earnest Google AppEngine got its fair share of promotion, too.

Google, the geeky technology company, has finally discovered the importance of good User Experience (remember stuff like the UI of AdWords?). Many of the speakers kept reiterating how crucial UX is. A nice insight by +Mike West: The time of the functionality behemoths (like MS Word) seems to be finally coming to an end with the shift to smaller applications (aka “Apps”) on mobile devices and in the web that focus on solving a small problem space really well. Providing in some cases gorgeous UIs, that are a selling point of their own. - And that users might come to expect after decades of suffering. :-)

Dart is to be watched. If this project takes flight, it will almost certainly replace GWT (see below). And things like CoffeeScript might quickly lose traction, with a neat language that effectively compiles to Javascript and has native implementations on popular browsers.

In the long run, GWT is dead: No single mention in the sessions I visited, apart from (anxious) questions by visitors of the Dart session. Google’s Dart advocate asked about Dart’s relation to GWT underlining that many former GWT developers are now working on Dart is telling, I guess.

Google (like other companies) is working hard on enabling small companies or even individuals to launch and monetize new cloud services and applications with a minimum effort (and risk). And earning their share in doing so (Google App Engine, BigQuery, Chrome Web Store, In App purchases, Google AdSense for games, etc.). In part, this is somewhat backporting the experience of the mobile app economy into the web space.

Whether it’s app or web, nowadays it has become extremely difficult to bypass Google (in contrast thinking back just 3 years, when there was no Chrome and no Android to mention).

Feeling out the Surface

Last Sunday (28/10/2012), after reading all the mixed reviews, I still was convinced I needed some personal experience with Redmond's attempt at regaining relevance.

After struggling with the absurd bugs of the online order process on for 30 minutes plus, I finally managed to get to the order confirmation screen. Microsoft, your online shop clearly resists being misused for such profanities as ordering hardware devices.

When the touch cover arrived on Wednesday, I was prepared to wait for another 3 weeks (as stated by the order process)  until the actual tablet would be delivered. But here it is, handed over to me by UPS on Friday morning.

Some personal impressions (from a heavy mac/iPad/Nexus 7 user):
=> Slightly clunky when coming from the iPad but with a nice metallic touch
=> The wide screen format feels awkwardly narrow when held in portrait mode; this seems to be a matter of size (or getting used to?), as I like it on the smaller Nexus 7
=> wide screen tablets are a peculiar form factor definitely requiring custom UI layouts, see => yey, I get real windows and a pre-installed command shell (kind of retro cool)!
=> Update and reboot - another heavy wave of nostalgia coming your way
=> Updating Office to production version is an optional update, hidden in desktop land? See => Tried to watch ZDFMediathek (German TV): Doesn't play quicktime nor the windows media and the flash player is excruciatingly slow for video
=> No Google+, no YouTube, no Twitter, no Dropbox (so no serious work with  this one), no Facebook - but hey, it runs Office!
=> Skinning Office to my personal taste is so important, that I am presented  with a pesky not touch ready dialog for choosing a skin even before getting to see the actual application
=> Yes, Office is a full-fledged, windowed, not really touch-enabled application not an app

And the touch cover? Haven't even taken it from its box. It's a tablet after all, isn't it? That said, typing on the wide on screen keyboard is a breeze. As a heavy tablet user, I do not see how this keyboard will significantly speed up my usage scenarios (which include creating content). But I'll give it a try later.

Microsoft's foray into the tablet space feels half-hearted for many reasons. They may still succeed in the long run (lower price, boost app market, leverage the Windows / Office / XBox eco system). But my guess is, Windows tablets will not have a thoroughly consistent user experience any time soon. So in spite of the bold design language of the user interface, "captivating" might not be a label you will want to attribute to these devices. Please try harder, Microsoft.

The Difference between Marketing and Product Design

The difference between GETTING the attention and KEEPING the attention. The first one might be achieved by being loud and boasting, the latter one needs to be polite and helpful. Always be aware where the first one ends and the second one starts. ;-)

Based on ideas by Alan Cooper and Tamara Adlin

The shy boy in the corner will not be noticed - even if he is a perfect gentleman. :-) Being charming means you need to cross borders. But once the girl shows earnest interest, be earnest, too. ;-)

Minke Map about Google+

This my first attempt at a map about Google+ and its ecosystem. Hover over the map nodes to see additional information. Feedback very welcome.

This knowledge map was created with an experiment in social knowledge mapping. - Please use a recent, SVG-enabled browser to view. :-)

+Maz Rashid Danke fürs Feedback! :-) Ich werde die Map bei Gelegenheit um die Mobile Clients erweitern. Für iPhone gibt es übrigens durchaus einen: Mit YouTube hast Du natürlich recht, aber ich hatte das schon unter dem Punkt "Competitive+" aufgeführt und wollte es nicht noch mal wiederholen. Ups, Deutsch, egal, zu spät für Englisch. :-)
