significant improvement over XP - for real !
Well. I think they are actually done a good job. I've recently switched to windows & (64 bit) as my main development box was running XP and it got infected with nasty virus ( that's another story ! ...)
I am honestly pleased with windows 7. Its much faster than XP (for me) and there are signficant inprovements with the UI which make it a pleasure to use. I used to find that XP was fast when initially installed and then it would slow down after a week or so. (I've tried Windows7 on a 1.0 Ghz laptop and a 3.4Ghz PC).
IMO the complaints about the hidden file extension and hidden menu are just silly and these can be enabled after a few minutes of playing around. Yes the user should not have to do this but come on - is that the best the auther can come with ? It Sounds like the author tried really hard to find three things he did not like.
I agree about the multi-touch (tried on a DELL tablet also also). The two issues that bug me are (a) Window Backup only lets you backup complete libraries and (b) there's a lack of desktop management ttools ( I can't find out how to change the taskbar or icon size and I'd like to be able to group things on the desktop).
However, overall Windows 7 is pretty good. I feel like i've got a new PC. Its faster, most things are easier and I've got much more disk space ! I never thought I'd turn into a windows fanboy !
