It's great to hear that you do intend on building mobile versions for SleepyHead. When the time comes, I'll be happy to do some serious user-testing (as always), although I don't write code. I just got my first iPad and I do have a pretty silly question: How would the data be imported to an iPad since there are no ports?
Pardon me if I'm asking a really, really dumb question, but I've only just started playing around with the iPad. I quite like it, but that seems to be my biggest naive user problem: Getting personal files onto the iPad seems to either require the "stuff" to be in my DropBox or GoogleDrive OR I have to have the thing attached to my computer. So, for example, it's not clear at all to me how to get photos off my digital SLR an onto my iPad without going through the Mac anyway. (I know: I could just take pictures with the iPad, but that's beside the point. The Pentax DSLR takes fantastic pictures.)
