Tom Mounsey: No Support for Windows XP means goodbye Adobe for me. I'm sick of being mugged by companies like Adobe and Microsoft milking us every 18 months to stay on their merry-go-rounds.
I use W7 and XP, you mention security, but that is for 80% up to the user. I you update all your software regurarly, etc, then XP is still very capable. In fact, W7 gives me more headaches as XP concerning stability and searching for docs and settings, etc.
