Is $250 for FEZ Spider kit a good value? You get a 3.5" color touch screen, you get camera, you get camera, you get USB host support, you get 16MB or RAM + 4.5MB of FLASH a lot more that I can list here. For FEZ Spider software, I wouldn’t even know where to start, so much more than you can use compared to the limited Arduino. Not to mention the commercial possibilities for FEZ and Gadgeteer, not just the fun side of things.
There is a new kit from 8-bit Arduino with far less capabilities in hardware and software than FEZ Spider. The kit is selling for $359.00 at makershed!! To that price, I say GHI should make the Spider kit $500 easy
In my opinion, even FEZ Ultimate Kit at $150 has more value than this Arduino kit! You be the judge: http://www.ghielectronics.com/catalog/product/265
