Every time I'm up to get a new phone I come this close to switching to iPhone. My wife has one, and I've switched to Macs. But there are certain utilitarian functions that keep me on Android.
As of the last two design revs, though, I also have an aesthetic aversion to the iPhone. Gruber describes the jewelry or fine watch-like quality very well. But I don't wear jewelry or fine watches. (Ok, I wear a wedding ring, but it's a plain band.)
Maybe I'm just a philistine, but there's something about old original Motorola Droids that are at this point beaten up and worn that have a really nice aged, aesthetic weight to them.
It's a sentiment similar to the one Khoi Vinh lays out here: http://www.subtraction.com/2007/07/16/designed-det but not quite, because I think smart phones become obsolete too quickly for 'designed deterioration' to be realistic.
Maybe it's more that I don't want to feel that precious about these objects. I like to be able to not have to worry that much about taking care of my phone, to be able to toss it around without worrying about damage.
Or maybe it's just an emotional, class-based aversion to luxury goods because I grew up in working class conditions.
