Samsung seems to have done it right (I am on my way to pick up one up) but the earlier Androids were hit and miss. I assumed I had choosen right when I went with an HTC phone, but I got shaftet and my Desire (the original one) never even got Ginger Bread (2.3) despite promisses from HTC. Now, not yet two years old, it has started to crash whenever I use the browser for more than a few minutes; hence the replacement.

I would love something as dead simpel as an Iphone, but IOS is far too limited for my likes (especially lack of sideloading, intents and services).
