Could you point me at the paid for equivalent for excel on Linux?
If he donated even a thousand dollars he wouldn't get the product he can get for almost free on windows.
Doesn't Excel run under Wine? That might actually be the better option.
(LibreOffice user here on Windows, donated in the past, but I find LibreOffice Calc really unpolished. It puzzles me because NeoOffice is really quite good on the Mac. I should probably just switch to MS Office.)
Certain versions yep :) . Although I'm not sure it's flawless. Crossover office is best if you're going down that route, or just put windows in a VM and run it there if it's crucial to your work. That's what I do.
