The upcoming Dell XPS 11 is being reported as having only 4GB of ram. Dell itself hasn't been very open about the specs. It's a hybrid that I'm very interested in because of the included digitizer pen. The 11.6" screen seems ideal for digital art. The smaller 10.6" Surface Pro 2 and the new 10.8" Dell Venue 11 Pro would seem to be a bit undersized for art work. My question is, will 4GB of ram be sufficient for digital art (ArtRage, Photoshop, et.al.) or should I look further for a 8GB tablet? It's going to be a lot of money for the XPS 11 and I don't want to make a big and costly mistake if the ram is going to be inadequate. What do you think?
