iPhone 4 looks pretty nice, really good specs, I found it hard to get excited about though, just don't like the same old homescreen and same old everything, that's one of those things I love about Android, it's the same operating system I had over a year ago but it has advanced so far in terms of capability and look in that short time.
Android devices are already on par with this offering in a lot of ways, processing power, screen quality, 3D capabilities and there are going to be even more powerful ~ 1.2GHz dual core snapdragons announced probably near the end of the year. The only real new thing it's bringing to the table is the highest resolution screen i've seen on a mobile, but is all that DPI really needed?
I have the same views and observations as you over the conference, didn't get excited at all.
With relation to the screen resolution thing, I was actually telling my friend about that earlier during the streams. For example, the HTC Desire's screen is awesome enough as it is, the only down side of it is the size.
The only major difference to current Android phones is the gyroscope addition this time around I believe? There was lots of talk about various apps (lol Farmville) but Android will inevitably get similar ones to these soon.
