I think every laptop you can by NEW, will work... I'm using an old Asus eee pc 900HD, it only has 900mhz and 1gb memory!!!! And it works!! I believe it's like 4 years old... The only thing I changed to it is the HDD to a SSD, because regular drives don't like vibrations. When I still used the old drive the laptop once slipped of the robot and fell about 1 inch to the ground and it stopped working(until I revolted). The ssd can handle 1500G so to conclude my story, stick a ssd in your laptop if the robot it is mounted in ever will be submitted to heavy vibrations like a rocky slope or something like that, else no ssd is needed.

Thanks for the SSD tip. I also think you are right on the memory, 2gb minimum. I think the key is Windows 7. So will upgrade my OS. My processor is just a pentium 4, but I will try it and see how it goes. Any one else?

I recently got an Acer tablet. It was $349 .. You can get them now for about the same price. On eBay there are no-name windows 7 tablets that are priced well too!

I really like the idea of a tablet for the touch functionality. Makes it a lot easier when demoing the product.

I also use the EZ-B with an Acer netbook.

Both of these have the C-50 (i think?) processor. With 2gb of ram. So they're not crazy machines at all. They run ARC just fine.

Keep in mind, the interface gets a little sluggish with SO many controls interacting. That doesn't bother me, and is expected.
