I'm about to release on-screen sketching in Auriga, and frankly, I can't imagine porting it to a non-PDA device with those new capacitive screens that need a finger, or a wide pen.
How has the iPad saved you money or time over a laptop? I would love to hear the benefits an iPad has other than just another cool techology that Apple has developed. So far I have not felt a 'need' to own one as it will be just be 'more stuff' I have to upgrade and maintain. How has it benefited YOU over what a laptop already provides?
