I just finished with it and then converted it all over to Sid and I was really impressed. The net install itself was a tad slow but it didn't miss a beat and the entire process from start to finish didn't really take all that long at all. Getting my tools, a patched kernel, Compiz, the Firewall, assorted gtk engines set up properly only took another few minutes. Hardware detection was perfect. I mean you could have pushed me over with a feather. Pretty nice for a beta and really damn nice for Sid.
I guess this is a beta of the installer that will be shipping with Squeeze next month. I still had to get my own Firefox and a few other odds and ends. Really nice though, I'll be keeping this one.
Anyway, anybody else try it yet?
