Lessee...

My first computer was a Commodore 64 ― had to cut grass all summer long to earn the money for it, then I got a Radio Shack PC-1 Pocket Computer, then a 128KB Apple Macintosh and pretty much one of everything in the store, then a GRiDCase III plus (yeah, when I was young and foolish I had disposable income and I disposed of all of it), then a NeXT Cube and NCR-3125 (running PenPoint) ― the latter pair made for the nicest computing setup I have ever had occasion to use, and I really wish my Cube was still running.

There, now I’m dated and feeling even older.

I'm using successfully an Olimex Olinuxino-A20-Micro board with debian wheezy on it with bCNC as a Gcode sender (can do some other things and it is evolving very well).

Why not just buy some dirt cheap laptop and nuke it, start fresh with Linux and call it a day? I'm seriously considering it.

Was thinking Raspberry Pi, but may not now.

I found a plethora of Dell Latitude notebooks from 2ish years ago. Third gen i5 with 4-8GB of RAM and SSD with a valid OS COA in the $250 range.

I snagged one of those plus it'll be good enough to do Google Hangouts video.

The main reasons of using boards like the Olimex or the Raspberry Pi are:

1) Cost Olimex board cost about 70 Euros with the proper SD card and the VGA adapter bought from Olimex
2) Power consumption a cheap 12V 1A or 2A is enough to power the board, the Arduino and the logic part of the Controller
3) Heath, as they use Tablet or Smartphones CPU+GPU they tend not to waste much heat so a static power dissipator is sufficient.
4) Space, they are little.
5) For the video part you could use an old TV for the Rasperry Pi and an old cheap VGA monitor for the Olimex

I'd love to use a RBPi.

If not for the fact I don't want to have to break out the PC for a quick part or fix something I screwed up in CAD/CAM at home, I'd be all about a Pi to do the cutting.
