Thanks, Simon, for your observation.
As you might recall, I have brought up my issues here, re: my DELL laptop and Apple PowerBook G4.
The DELL, with Windows Ultimate 7, has been virtually trouble-free, and it is second-hand. The Apple, also second-hand and a much more expensive laptop, is great for photos; however, more and more apps and webpages are unavailable to me because it will not upgrade.
I love my little, cheapie DELL.
