First off, I can't stand Microsoft and their demise can't come quickly enough for me.
Unfortunately though, I really like this.
I don't understand why Apple has resisted grouping activities on the iPhone user interface. I'm sick of searching through pages and pages for apps (and Spotlight searching is slow and cumbersome).
I hope that the 4.0 upgrade really is an A+ effort and completely overhauls what's now looking like a tired interface, one that was a fantastic (mindblowing) first effort, but needs to adapt to the changing role of the device.
MS has had the advantage of starting from scratch and addressing issues that probably were not on the Apple radar 4 years ago (countless apps for one). Apple needs to, and I'm sure will, do the same.
I'm pleasantly surprised. It's a refreshing change of direction if nothing else. For too long Microsoft has based its smartphone strategy around enterprise. It's little wonder that their marketshare has dwindled.
Of course, it's hard to judge a mobile OS by a handful of screenshots and videos. I can't wait to try it for real.
The other question is - now that Windows Phone 7 Series has been revealed, how many people will be willing to buy a Windows Mobile 6.5.x phone? There's no guarantee that Windows Phone 7 Series will ever be available for older phones.
Although I disagree about wanting to see Microsoft's demise, I agree for the most part with these two posts. It's nice to see a refreshing take on the smartphone UI instead of seeing "How many application icons can I fit on the page" mentality that we're seeing today.
In addition, I find the OS very "pretty" -- something that we've all long said about Apple's hardware.
