sure! why not? i mean it's a good computer that you'll like to use more than that VAIO of yours. You might want to upgrade the ram to 512MB like minimum, if your planning to put OS X Tiger or Panter or even Jaguar your going to need more RAM, if you already have OS X on there, it's going to be slow with out the RAM, OS X loves RAM!!!
OS X is like being in a mud pile with pigs eating up everything you can get...
And Windows XP is like having a cleaning lady dust every 2 seconds!
The MORE RAM you have for OS X the better!!!
DEFINITLEY BUY IT!
why not? $350 is not that much!
