I'm using 7077 too. 7077 is an escrow build which means it has to better than 6801. yes, a lot has changed since then. 6801 was an alpha/pre-beta build which means its buggy, and some features aren't even unlocked yet (remember the superbar?). While on the hand, 7077, being an escrow build would be the final stage before an RC is introduced, they basically look for show-stopper bugs. Compared to vista, the management and development of windows 7 has come a long way. I mean, remember Vista RC1, they had a huge bugeven then. So far, with 7077 my experince has been quite satisfaactory. But what's bad is, when booting I get so nervous that my windows 7 won't boot up, then i've got to reinstall my whole drive! Plus, when I've installed 7077 it's quite hard meaning that I have to backup my whole drive. It's not really hard but it just takes a long time, soecifically, 80 minutes . Then I reformat my hard drive, wow windows 7 NiCe!! O oh wrong driver, repair startup, system restore. Nope, doesn't work----so have reformat again . Then reformat, brake, reformat again! But other than reformatting for 3 times, I'd say Windows 7 7077 is a pleasurable experience. Plus the only bug I'm getting is my wlan card driver bug. And everything is quite staifactory. Tip: if don't want to reformat again and again, try using backup and restore of windows 7 instead of reformatting then a new install. It's actually faster with backup and restore.
