Next you are going to start praising iconatain's range of 'Amiga' tablets.
Btw I think Amiga tablets look nice.
Also there is nothing 'bog-standard' about the x1000. How many other custom designed ppc boards are out there with a Xena chip on board?
There are Xena add-ons available on Varisys website. You can order one and have Xena (XMOS) on Amiga 4000, PC, Macs, anything.
I also think the X1000 will be worth more than the Sams in resale value because they are different to the Sams (see above). I think it is perfectly possible for the Nemo boards to increase in value. Some of the most desirable collectors items were financial failures that later became cult icons. Thus increasing in value. An example of this is the Walker.
The original price for the Walker was much more than its current price at eBay.
