I love my SP3, but the new Wacom Companion 2 is pretty slick. If you can get past the price tag, it has everything I wanted in the SP4. Broadwell processor, next generation Intel HD 6100 video card, 13 inch screen, 16 GB or ram and a 512GB SSD for the top of the line model, and of course a Real Wacom Pen. $2500 is hard to swallow but the fact that you can connect it to any computer and use it as a Cintiq Drawing Tablet on a host machine, makes it somewhat future proof for artists.
