My wife is only 4' 10", and consequently finds her 15" PowerBook a bit
too heavy, so she plans to get an iPad for portable use in her second
career as a playwright.

I'm not planning on an iPad at present, as I have a 17" MacBook Pro
that I don't find a burden, and an iPhone 3G, but, as chance would
have it, I'm just now setting up an LLC to develop software, mainly
for iPhoneOS, but also for companion apps on Mac OS X and (yuck!
ptooey!) W*nd*ws. I'm a bit of a latecomer, but I've identified a
couple of niches where I think I can produce something better than
what's now on offer. (Some openings at present exist due to a good
many hastily ported PalmOS applications by people who haven't a clue
how to make use of a real operating system.)

iPhoneOS is pretty easy to master /if/ you already know Cocoa,
preferably at the Leopard level. (iPhoneOS omits outright many early
MacOS X features that are, on the older system, merely deprecated. It
also omits some newer features, chiefly garbage collection.) Alas, I
started out without any MacOS X experience at all, except in Java, so
I'm having to learn Objective C, Cocoa, XCode, and Interface Builder
all at once, which can be a bit overwhelming.
