A quick jaunt over to SonyStyle.com and you'll find the flagship Sony Vaio VGX-XL1 Digital Living System. Sporting a 200 disc DVD changer and Windows XP Media Center Edition 2005 w/ Rollup 2, this sleek looking system is a flagship of home entertainment integration, showcasing exactly why the My DVDs feature was added in Rollup 2.
That's the good part- here somes the less stellar: The system ships with only 512MB RAM and 64MB of on-board video memory in a GeForce 6200. Fine for 80% of customers, if you're buying a $2300 home entertainment addition, you should at least get 1GB and 128MB of memory, respectively. A 50% off offer on a paired receiver with WMA Pro 7.1 audio support would be another nice addition or even cross-marketing with a Digital Walkman. But alas, these are separate organizations under the Sony flag so I guess that's a non-starter.
Back on the plus-side, the thing supports just about every DVD burning format including dual-layer (no HD DVD or Blu-Ray support... expect Blu-ray only in an update in the future is my guess). If you're rich and have the moxy, this is a good system for you. Given the specs, it should serve you into the Windows Vista timeframe as well.
