Actually, Jeff's opinion is a bit more balanced that you might think from what I wrote in this weblog. His frustration threshold though, is quite low, and he gets mad pretty darn fast when things don't work.
Someone sent me some pointers to some Linux games. I'm going to try and get some installed this week. If he gets a good selection of games that he likes, that run under Linux, that will greatly contribute to a favorable impression. And, frankly, I'm rather hoping to win him over.
I'm also thinking of CrossOver office, and wondering whether that will be enough for him to run some of those Mercer Meyer games that he likes. Crossover is on my list of things to experiment with.
