OK, that was a weird moment just for a second. I was thinking about the testing I've been doing on the Ultra 20, and decided that running GeekBench on my iMac running Windows XP would be a good way to test, compared to the Ultra 20 running it natively.
Could I remember what the tool from Apple was called that would let me do that? No.
It took me a few minutes to find out, because without a name, it was difficult to find amid all the other stories on using Windows XP on your Mac. Why don't I use it? Because I have Parallels - and trust me, once you've used Parallels as a solution for most of your Windows XP tasks, using Boot Camp feels clumsy and restrictive.
