Geek.com has posted a video introduction to Windows 7:

Windows 7 will not officially beta until some time in early 2009, but we have been playing around with it for a little while now and wanted to put up some video of it in action. First off, there are some UI changes. The Ribbon UI (from Office 2007) has been added to Paint and Wordpad. Additionally, the calculator was upgraded. So nothing too huge, but some nice incremental updates.

So far the change in Windows 7 that has generated the most press has been the Superbar. This is actually locked in build 6801, probably because it's still in its very early stages, but someone figured out how to unlock it. Once it's unlocked you can see that it's flashy and functional, but not that different from the standard taskbar. The version on display at PDC was improved and it should be even better before the beta, once it's closer to being finished.

Everyone has also been talking about Windows 7 landing on netbooks. After all, Microsoft's solution for netbooks has been to put XP on them and that just won't do once the new OS is out (XP will be about eight years old at that point). So we loaded 7 up on Lenovo's IdeaPad S10. The installation went extremely smoothly, but I had a bit of trouble with WiFi down the road, some tinkering would probably solve this, but more examination is necessary. Aside from this, preliminary testing went through without incident. At idle there were 33 processes running and physical memory usage was 41% of the system's 1GB.
