I still haven't fiddled with it too much, because the first T7200 was toast. Now I have another, stable one. Seems the VMs are running a bit faster, and I can enable both cores, too. I'm running XP SP3, Fedora, and even Puppy (really fast), all on Virtualbox. I've also attempted a hackintosh VM, but to no avail. Can't say if it's worth it (at $75 on eBay). I'm already thinking about a new laptop sometime, since my battery's wearing down and I'd be happy with something a little lighter and faster. Then again, this thing's been a real workhorse, I have to say.
