I’ve mostly found alternatives for all the programs I used. The only area where I’m not quite satisfied is a music player; I used foobar2000 on Windows, and I haven’t found one to match it yet. (I’ve settled on Quod Libet at the moment, though its UI is a bit lacking.)
WoW works, but I seem to be paying a ~10fps tax for running it under Wine. It’s a pain, but it’s still playable.
I still have XP on a partition, but I haven’t yet run into anything I need to boot into it for. This is a promising development.
I’m looking forward to Hardy Heron’s release. It’ll come with the newer nvidia drivers, which apparently improve performance. This will be appreciated, as I’ve been unimpressed by canvas in Linux-Firefox so far.
