Is there any improvements in the actual Wacom Digitizer hardware between the SP1 and SP2?
My main requirement is for drawing (Manga Studio, Artrage) and usually I make drawings with about 30-40 layers at 3000x3000 pixels (144 dpi). I don't know if 4GB RAM will be enough for this.
hardware wise, if im not wrong, sp1 and sp2 main difference is the new lower power consumption cpu, and more memory options.
4gb of memory is still good plenty of work.
