Yes, for crying out loud, some people are judging a Windows operating system based solely off an undeveloped, developer preview build. It's not even done yet! Microsoft got the Start Screen pushed out for the DP so developers can get used to it. There's obviously much more to come. Microsoft showed off features that aren't in the DP during the BUILD conference a few months ago. We haven't used those features yet.
I mean, the concept of being able to see ALL of your installed programs and apps visually is great. I've installed Windows 7 multiple times and have configured Windows 7 installations and have always put every relevant program in the All Programs list of the start menu. That's sometimes in vain since I've had people tell me they've never used the start menu. Man, oh man, Microsoft wasn't kidding when they said people don't use it anymore! I've seen start menus that are a wild beast of folders and nothing is configured or moved around. The AVERAGE user doesn't do those sorts of things. They don't delete superfluous folders or move things around or change the size of the start menu so more is viewable. Simply saying the Start Screen is going to make Windows 8 a flop is one opinion out of millions. The average user might actually know what is installed on their hard drives now. Saying metro design is repugnant is one opinion out of millions that have already used products with metro design and love it for it's simplicity and visual appealing aspects. Just because there's a portion of Windows users that are power users that don't like metro doesn't mean that average user is going to dislike it for it "lack of customization." What's the need to customize the Start Screen? There's going to be color options, grouping options, pinning options, and potentially DPI options. But there's not going to be widgets that people really don't use. There will be apps for that that replace those widgets with something better.
Speaking of such, I don't ever see average users use desktop gadgets ever. Every install I do, I always install a system monitor gadget, put on the slideshow, weather, and an antiviruses' gadget. After some time and I do work on a particular installation, I always see most of them gone. Usually the weather gadget is left on there. That's probably why Microsoft isn't supporting the Live Gallery anymore.
Gee willakers you guys!
