That is encouraging! What's your opinion of Windows 7 vs. Vista SP1? Buggy?
6956 is buggy. It's still a alpha/pre-beta.
The interface is a bit more polished over 6801, but performance is a bit off compared to Vista SP1.
Aero can slow down occasionally (this isn't on a MBP or any Apple product, it's on my gaming PC with an 8800GTS 512 mb). I used the drivers that came with Windows 7 and drivers from Nvidia, both yielding about the same result (actually, I found it a bit more buggy with Nvidia's drivers, but they were intended for Vista).
Boot time seems to be better, and the new boot screen is nice. It's about comparable to when I first installed Vista 64-bit Ultimate on a fresh install. But boot up does seem a tad faster, especially if you have gadgets on your desktop. In Vista, Windows Sidebar can really impact boot time. It seems a lot better in Windows 7.
One thing that's great is that Windows 7 only load necessary services and loads services when you need them. This is especially noticeable in the task manager, with the number of processes around 33 (I don't have anti-virus installed, since I don't intend to do much with it). Supposedly, 7 will unload these services when you don't need them anymore. Hopefully, this means that we don't have to go into services.msc and configure what services are running.
Also, there is finally a wallpaper switcher. It acts just like the one in Mac OS X, and all I can say is, "It's about time!"
There's also a few new games. Not really new, but if anyone remembers Internet Chess, and Internet Backgammon and another Internet game, that was in XP. Well, all the Internet games disappeared in Vista (since ALL the games in Vista were recreated, as many of the games in XP had been around since the Windows 95 era and a few I think in Windows 3.1, like Minesweeper and I think Solitaire). Well, they are back. I don't know if they were in 6801, but they're in 6956. Unfortunately, since this build was never intended to widely released, nobody was playing, so I can't comment on how they would run.
Overall, the build is a good one. It's kind of obvious that it was never intended to be released to the public. It makes a great presentation build.
Build 6801 was supposed to be a pretty stable build, but many of the features that make Windows 7, Windows 7, were disabled by default (like the superbar, and aero peek) and were never supposed to be enabled by us. In fact, Microsoft never showed of 6801 with all the features. I believe they showed of 6933.
I think Beta 1 (supposed to released in January, I think the 13th) will be much better in terms of stability and overall buggyness. This build is probably pretty close to what Beta 1 will have in terms of features (since in 6801, some of the new aero features seemed incomplete, such as aero peek). However, I'm sure quite a few of the bugs will be fixed. I already have a few that I will send to MS if they're not fixed by Beta 1 regarding explorer refreshing the folder's contents and stuff like that.
