This doesn’t really slot in to any of the Windows device categories here. What it is essentially is a no holds barred portable workstation with an outstanding (we certified the DreamColor version a few weeks back) display and is VERY fast.
It’s also VERY expensive, but I would think the majority of these are being purchased by companies for a very specific worker.
Two other comments are that the keyboard felt a bit on the mushy side, and that battery life was nothing to crow about, though given power/performance in line with others.
If you need something with these capabilities (especially the DreamColor display option) this is great choice.
