Think I will wipe the drive and go back to Snow Leopard.
Pretty unimpressed, don't like the new scrolling (even it you change it back it is different somewhat), bunch of applications don't work now, such as all my MS office apps, Coreldraw, Expression, Palm, Parallels - so the entire virtual PC is down and all PC programs.
I know I could upgrade some of these and get them going, but then there is the cost of doing that. Haven't even tried to use old printer drivers yet, but that is likely a bust. I thinking mostly the operating system has just been dumbed-down.
Don't really like the new mail interface.
Oh well - many will like this upgrade, but if you have a lot of software from over the years, be very careful...
