Hey all, I am a recent switcher from mac to PC - I still love Apple, the Macintosh brand, OS X, and iPods, I just really like upgrading and gaming, so it fit my needs. Anyways, my new Dell Studio XPS has come with Vista x64, but I installed XP x64, because I really like XP. Now, I am wondering if mayve Vista x64 would have been a better choice. Does anyone have a lot of experience with using Vista x64 as it exists today? I am wondering about application support, drivers, security, etc. Will I find it very different than XP? What I really like about XP is that I can modify just about anything I want with the hardware or software, and I don't want to lose that freedom. Thanks for your input!
