Very first iPhone vs the first Android.
Oddly enough, the Android has no headphone jack :P
A really interesting video nonetheless, all jokes aside.
It's too bad that most phones with a landscape slider keyboard was a lower end version of the non-keyboard phone. The Desire HD was released the same time as the Desire Z. The HD was the high end phone and the Z seemed mid-ranged in comparison.
The Nokia N97 had the best physical keyboard I have used on any phone. Landscape keyboards have the advantage of the keys being spaced apart, so it was easier to type than on a BlackBerry. The Desire Z keyboard was not quite as good. I found the keys to be too stiff for my liking. The N97 had keys that were easier to press.
Still, I was able to type on the Z without the need for autocorrect. Being able to feel the key before I press it enables me to actually avoid pressing the wrong key. You don't get the tactile feedback for touchscreen keyboards.
When I upgraded to the SGS3 in 2012, I had a horrendous time trying to type. After 6 months, I gave up and had to turn on autocorrect. I thought that in time, my typing skill would improve enough, but it didn't. In comparison, it only took a few weeks to get used to the keyboard on the N97 and Desire Z.
