It'll be good eventually I'm sure. However I've never stood in line for something and never will, it just makes you feel like a jackass nerd.
Besides it's not going to be that revolutionary and not required at first, just like XP wasn't until a few years after its release. It will be better than XP but getting it as soon as it comes out seems unnecessary.
On top of that I'm not a reformat kiddie, so it's not like I'd need to reformat anyways. People that say you need to reformat every month are just retarded, it's completely unneeded and a pain in the ***. I'll reformat ever 6 months to a year, and usually I only do it to wipe out all of my installed programs, not because of any slowdown or problems.
I dont know how people can say that XP is that breakable, it just isn't and you're using the computer in the wrong way or something. I give my computer tons of torrent abuse and deletes/copies and it still runs as fast as it did since the last reformat.
