Short Shameful Confession
I’ve been running Winows 7 on my work laptop for a while now, and I’ve been really happy with it. Some of this may be that XP was creaky and Vista unconscionable, but 7 better than both at their respective strong points, and in some ways better than OS X. It’s the first Windows install in, oh, ever, that I haven’t had to reboot 7+ times to pick up all the patches, and mostly things Just Work™ without needing to tinker.
