I bought a Sony Vaio 15 Flip ($1200)[1] new vs. a MBP, Surface Pro 3 or Wacom Cintiq (needs a computer) for drawing. Artists are still looking to buy them at $1400 to $1800. It has a large drawings surface vs Surface Pro 3, a dedicated GPU, lots of ports, and a great screen. It runs my CAD programs (Rhino, MOI and AutoCAD Fusion) sufficiently for an i5-based notebook. It has some other great screen positions for just browsing. It a very sleek and well-designed unit. I can see how Jobs would admire them or be inspired by their innovative designs. Just look at the PSP vs. the Nintendo Gameboy physical design. I did consider an Apple Modbook [2], but it was too blocky, expensive, and going to a third-party for a modded Macbook didn't feel right, although they are Apple-endorsed and sponsored now.
