I've used a Gateway XC210S tablet pc for 5 years now, and have loved it. However, it's time to look for a replacement. I'm considering buying a Motion Computing M1400 from eBay for around $200, but my budget allows for around $700. I've seen the large touch-screen all-in-one computers at Best Buy from Gateway, Dell and HP. None of them are wacom systems, though, and I can't get any information about pressure-sensitivity. Has anyone tried these systems with Photoshop, Sketchbook or Artrage?
