FWIW software installation and updates on the tablets (for mainstream items) is point and click through Application Manager which is built in. (and not closed off too just Nokia repositories)
My mother got a 16gb Touch for xmas yesterday that I helped her setup. Small, slick and easy -- yes. But I would be bored with it within a week without the "additional apps" that people are now counting on being here in Feb. iTunes drives me insane as it's bloated and picky about formats and requires an iTunes account (with Cc) for things like coverart downloads. It would be the first thing I would look to replace.
