Windows 7 dissapoints me beyond belief. In fact, teverything about it is the "worst case scenario".
1. Home page.. I can sum it up in "WTF". The home page that takes up about 80% of the screen (so even big screens look gimped, small and shifted to the side), with a huge area on right and up completely wasted for nothing. Ugly plain-colored squares, with no design consistency (big, small, long, tall) with pieces of information that make no sense.
2. Social networking - as for me, I really don't give a flying turd about my neighbor's ugly kid drawing an image of a bird on the wall with his drool. Nor do I care that much about viewing hundreds of pictures of my friend visiting his grandma. Thanks for covering my home screen with that.
3. Xbox - I don't even have an xbox, nor do I plan to buy one. Neither do most of the business-oriented people who buy a PDA. And even if I did, would I really be so obsessed about my "avatar" or "points" or whatever they use, that I need it on my home page?
4. Emailing - the heart of a PDA. For some people, even more important than the calling itself. By looking at the presentation videos 7's email system is complete trash. It gives you no real "sense" for the inbox, there is no good view to browse your emails properly. Swiping through pages to see "flagged" "unread" on different screens creates a feeling that you're not getting the whole picture, and you're missing stuff. Besides, it has no good integration with contacts that HTC's Sense provides pretty darn well.
5. Interface in general - animation effects blow. They are kind-of OK for today's standards, but when 7 is released, they will already be boring and plain. They are not looking forward, the "flow" of it is already outdated and will be completely destroyed by any new interface that Android or especially Apple will no-doubt deliver in near future. Besides, how awesome it is to see parts of words all the time? "Peop" turns into "ople", so if you slide left-and-right real fast, you can actually see a whole word..... freaking idiotic.
6. Customization... I'm just speechless. This is the only thing that I could raise as WM's, perhaps, only advantage over Android and iPhone. Now they are officially going over to the Apple's way of treating customers like money-packed down-syndrome drooling kids that fall into a seizure when they hear words "cab" or "tweak". After hanging in xda-developers for so long, and writing my own stuff for the PDA, this alone is way more than enough to make me never even look at WM devices again.
7. "Copy and paste" and "multitasking".... I cannot believe that there is even a controversy over WM device having those 2 features... I don't even know what else to say about this. Insane.
Microsoft is obviously a huge Apple fanboy now. They are accepting their market strategies and their development practices and are scared shitless to look ahead and develop something brilliant.
At this point, with current info, WM7 is nothing more than a bad, extremely poorly designed iPhone interface mod. It's already outdated, already looks inefficient, boring and just waiting to be forgotten. Heck, age-old HTC Home plugin looks way better than WM7, and is actually more useful for everyday tasks.
