I just finished flashing my HD2 with ICS and must say that I am a bit tired of finding out that the whole design (icons/apps) is totally rehauled. Somehow Google doesn’t have a keen sense on what they want to implementate GUI wise. Android 2.1 was a overhaul regarding the icon style, and with ICS they redesigned everything again.
I don’t think it’s really a improvement, although you probably adjust to the new changes. More a pressing concern is that the Design team has not a real consistent vision and this forces users to re-addept every time they buy a new phone. Also as a developer it’s quite frustrating, since you need to spend more time on the GUI side of your app. Not that that is a bad thing, just that is annoying.

Well, after a few days playing around with ICS I must say I am impressed by it’s speed and lovely design. 🙂 I love it!! Still don’t like it that there is so much change again, but the system itself is gorgeous and fast!
