I posted already that the iPad will end up being cool because of the apps that aren’t out yet, mainly taking advantage of its larger-than-iPhone size.
Omni group is planning 5 apps for the iPad: OmniGraffle, OmniOutliner, OmniPlan, OmniFocus, and OmniGraphSketcher.
I use one of those on a daily basis, one on a frequent basis, and one occasionally. This is already beyond the iPhone, and it’s because of the screen size. You wouldn’t want to use most of those on such a small screen. (There is an iPhone app for OmniFocus, thankfully.)
I wanted to know the screen resolution, so I looked it up. It looks like Apple either doesn’t know, or doesn’t want to say. They call it “high-resolution”, meaning, “well, it looks pretty good to me!” or maybe “our customers aren’t smart enough to deal with numbers.” Meanwhile, another site listed it as a “weak” resolution of 1024×768. If that’s really it, I wouldn’t call it weak. I’ve done a good bit of CAD work with that resolution. I could put together a full-blown utility capture system to run on that! Hmm…field services…3G wireless handheld…could work.
