I just spent a good half hour again reading through this discussion thread and catching up. A very interesting progression over a year's+ time.
The push to cloud computing, in the meantime, has been given a significant boost by Apple with its iCloud. I own the last Mac Mini with a superdrive capable of reading CDs and DVDs. The newest ones have no such disk reading capacity. Everything will have to transferred through the cloud or by a USB or other connection. Apple's assumption seems to be that computing is now ubiquitous in several devices we may own - a smartphone, a tablet, a laptop, a desktop - and things will get way too complex and confusing if John Q. Public has to be constantly synching and copying over files from device to device. Some say Apple is building its own closely integrated universe which more or less traps you once you are sucked in. I've used Macs since 1984, so I'm probably sucked in by definition, but I am not thrilled with the prospect of having backups of most of my files in the cloud (i.e. at external server farms).
Some say we are rapidly entering a "post-PC" era where we'll need to rethink our assumptions about personal computing in the same way that cell phones forced a rethinking of having to only make calls on a landline, either at home or in a pay phone booth. So, whatever our druthers, the confluence of technological advances and the integration of new features ('pay at checkout by flashing your smartphone at this UPC or whatever') produces a kind of evolutionary march. Ten years from now will anyone be able to make a retail purchase purely by cash or without a smartphone? But enough on that OT stuff...
I have a question for those of you with iPads: have your found that some files read better at full page size than others? What I mean by that is: can we identify a scanning resolution and/or dpi that works best for viewing comics on an iPad? I've noticed on my desk computer's monitor that image clarity varies strongly from 25% to 50% to 75%, etc. Moire patterns set in at certain viewing sizes, but not at others. Does this prove the case on iPads as well?
