I used Acer Aspire One, nice little computer, but for me the screen was to small (not enough data displayed for me - I like to follow one pair through many time frames), now that I have a larger screen, about 4 times as much data fits on the screen and is very nice to work on. But to do basic things on it was OK, 1 Gb, older Atom processor, Xp, MT4 was working nice. Of course, it all depends what you want to do. I managed to crash MT4 on my home i7, 8Gb beast, lol.
