I'm considering my options for a (sniff!) replacement for my slowly dying 12" PB G4. Since buying an iPod touch / iPhone, I find my PB to be rather immobile, that is to say it usually stays on my desk and even when I take it out to say a coffee shop I tend default to just using my touch unless doing a lot of writing. I'm off in the Fall to do field work abroad, so I'm considering a setup that includes an iPad and a MacMini. Seems for around the same price as a 13" MBP I get a much more flexible setup. Sure I have to buy a monitor, but that seems to be worth the cost. Any thoughts ? I'm assuming here that the iPad will meet my needs while doing field work, which remains to be seen regarding how good the onscreen keyboard functions. The specs for the lowend mini & MBP appear identical, what am I losing ?
