It seems every time I upgrade my media center, this happens. Sure, I can go for a year,  maybe longer without any major developments, but with the advent of dual-core processors, I find myself wanting.  Never is that more true than with HP's new Media Center PCs including the new Athlon64 X2 Dual-core processor.  Sure, MCE isn't native 64-bit today (but start asking your hardware manufacturers about drivers for the future) but you'll still get great performance.  I don't even mind that these look like Apple.  White and silver are the "new" black.  How long until Black is the new white and silver again?  I give it 10 months... tops.

Update: Thanks to Brian Hoyt for pointing out I was baited on this one. While HP's site says clearly "From $799.00 (after rebate)*" and directly underneath calls out "Powerful Athlon 64 X2 Dual Core" the combination of fine print and their configurator for purchase adds over $500 for the dual-core, putting the price at over $1300.  Ouch.
