[Inkscape-user] OFFTOPIC: Graphic designers computer setup?

This is way offtopic, but I'm learning Gimp and Inkscape and planned on buying a desktop PC soon and then trying to get some work in graphic design - maybe in a printing company for starters.

However, during this learning phase, I've noticed that my 750Mhz / 512MB Ram laptop is doing quite well under Ubuntu.

Do any of you think it would be as practical to work on a laptop exclusively?

Thanks for reading, Jarlath
