I am currently taking 7 for a test drive, if someone came to me and said,
(quoted from linked review page)
"...try launching two Windows at once or loading two Internet Explorer windows. Try deleting one large folder of files, and then while that’s taking forever to delete, try deleting another."
I would say your hardware must be severely lacking!
I currently have at least a dozen Internet Explorer pages open... running like greased lightning. I have actually run my DVD backup software whilst browsing in this fashion with no noticeable performance issues.
I have used 7 to copy and transfer upward of 100 high resolution photos from my 8mp camera to a 2 1/2" external HDD, job completed nicely.
Highlighted and deleted multiple files, large and small, the OS didn't balk at that either.
I haven't yet had the chance to look at the very comprehensive "Performance Monitor" included with the OS, but I will when I decide to drive it hard. At the moment I'm still enjoying cruise control.
Sorry to that Scott Whoeveryouare, I couldn't make it past the second paragraph. His experiences with 7 and my own had differed too much by that stage!!!
