I am looking for a tablet device to function as a digital sketchpad. One that I can use on the bus to draw, on-screen.
After reading up on the HP Slate, Cintiq, and various muddlings of iOS apps, I am really interested in finding out about a [hopefully Android] [tablet-ish] device that can be used as a portable, digital sketchpad. The best looking candidate pushing the limits so far is the Viewsonic View Pad 10 (dual boot Android/Win7); although there is no stylus support out of the gate.
These devices above can tout various elements of their interface that would come close, but the HP Slate seems like an over-priced, underwhelming device (understandably, it is not targeted at the niche I am asking about) as it's digitizer is sub-standard and the processor running the machine is low end for graphics software. The iPad offers drawing apps, but it's not built up (by design or through peripherals) around stylus input to my knowledge. The Cintiq is amazing...ly expensive and out of range but has the core functionality I would be interested in (unfortunately, though, without a battery it is not portable and is AC-dependent).
Are any Android partners looking like they have a product that will push into this space? Of course this is less a question about UI as it is a question about both the tablet itself as well as the peripheral and the degree of sensitivity. Basically I am looking for a portable, digital sketchbook to facilitate high resolution, detailed drawings to be rendered by stylus.
