Interfacing with Arduino is very cool.  It is high on my list of things 
to play with (as time permits)

Now in case you ever need anything more industrial/powerful (but more 
costly) here are a couple of things I have been kept a wishful eye on 
for a couple of years (but I have not yet had time to play with). I 
share this on the random chance someone gets interested in it before I 
get a chance to play - hopefully early next year.

200MHz ARM9 CPU;  32MB SDRAM (64-128MB opt)
8MB RAM Framebuffer;  able to drive TFT-LCDs via custom FPGA
5K LUT FPGA  <----------------
Boots Linux 2.6 in about 1 second <----------------
1 10/100 ethernet port,  2 USB 2.0 (12Mbit/s max),  1 SD Card slot

250MHz ARM9 CPU;  64MB DDR-RAM;  256MB SLC XNAND Drive
Customizable 5K LUT OpenCore FPGA <----------------
1 10/100 Ethernet,  33 DIO, SPI and I2C interfaces,  8 TTL UART, 1 CAN bus
