I want one of these. Right now I cannot make up m mind. I met a guy here from Microsoft and he said the Surface Pro will give me between 5 and 7 hours working in Corel Painter or other graphics program. Not bad at all. I read good things about the Samsung tablet, the Smart PC Pro and it has similar battery life and some claim to get very good pressure sensitivity with Painter and Photoshop. Asus TF810 right now seems to have a problem with pressure sensitivity with Painter and Photoshop...but they say that when Wacom releases the driver then that problem will be mute. But the Asus will have a much longer battery life with and without the keyboard dock. Being that Corel Painter is the sole reason I want one of these tablets...can anyone point me to a site that compares them...or is there someone here that can make the case for an artist for the Surface Pro. Right now the only drawback to the Surface Pro is that it has the 1080 resolution and I wonder, because the tablet is slightly smaller than the 11.6 Samsung and Asus..and even on those tablets some artist are saying that the UI is a bit tricky because some of the tool settings are hard to click on because they are so small. Anyway....I would be grateful for any feedback anyone might be able to offer on this subject. Thank you.
