You probably want a PC with a large hard drive, a DVD drive (which will also play CDs) and a DVD-RW drive (which will also burn CDs), 1024 MB (1 GB) of RAM, dual processors, and the Windows XP Media Center Edition operating system. Do not wait to purchase a PC with Windows Vista, as that OS is likely to have problems with its initial release. Windows XP systems will likely be sold at reduced prices when the non-beta version of Windows Vista is released by MS.
