As for OS goes.. the list is missing the XP variations.. it combines Home and Pro into the poll...
however, under XP.. Home and Pro are moot so long as people are using XPSP 2 IT Install (266 mb).. Trns Home and Pro into Pro SP 2 reguardless of what splash screen states.
Now under the Pro edition, there are 3 versions released prior to XPSP 2
there is the XP Pro Corporate, XP Pro 64 Bit Server Edition and Media Center Edition.
Under Media Center Edition, there are 3 versions which were sold separately on prebuilt machines..
MCE2002, MCE 2004, and MCE 2005
I happen to be using Windows XP Professional Media Center Edition 2005 with XPSP 2 build 2180 IT Install.. runs extremely stable. No lock ups or crashes.. havent had to reboot my system since I installed it in Nov 2004 when it was released.
