In this day and age, a pocket tinkertoy that only plays chess is nearly obsolete.
You can run a plethora of softwares on a netbook ... or if you want something even smaller, buy a smartphone and run Master/IM strength level engines on that.
Could you clarify what your needs are, exactly?
I only found 1 thread and that didn't fit what I was looking for.
I am going to invest in a chess computer. What I am looking for is a digital one without physical pieces. I want one that last a long while even if I improve too National Championship level (not likely but anyway :P) anyone that can recommend one?
Best regards
