I have Photoshop 6.0 (old as hell, I know) that a friend bought for school then never used and gave to me. If I ever need to use Photoshop more seriously, I will buy a new copy. If I am unable to afford it at that time, I will make do with Gimp or my old 6.0.
I own it but it's the version I originally bought way back - PS7 - so far I haven't seen the need to get anything newer (tho if I could afford it I probably would - after a new computer to run it on - lol))
it's logical for student to do this ^^ it's not possible to buy a software for this price. Adobe know how many copy are pirated but they know if you wanna be freelance or professional you'll must buy a legal version so they win both
