HailMary, there is actually a bit more to A64 as a DTR offering than meets the eye right now (more on that as more information becomes available on the web). As an indication, from your link:
The new Voodoo ENVY m:855 makes other notebooks look like they’re standing still. The first to feature an AMD Athlon 64 for notebooks, this desktop replacement is like a finely tuned F1 race car. With features such as the ATI Mobility 9600 Pro, an AMD 64 Bit Processor – and battery life that in real world tests bests our Centrino notebook, you better believe the engineering that went into this baby was well worth it. The Voodoo ENVY m:855 bests all desktop replacement notebooks in almost every category – it’s lighter, smaller, faster and once you go 64 bit, you never go back.
A64 is currently the best offering for the DTR/high-end notebook space, and this space is certainly not tiny by any means. I see a lot of potential here.
