Snob.
I buy whatever does the job best. I couldn't give a flying **** what someone else has chosen to get, and neither do most of the other millions of owners. The only people who do obviously have issues with their own self-image, and the way they think they are perceived by others. Says loads about their personality problems, and nothing at all about my using Apple products. I arrived at my decision after years of using Apple computers in a professional environment long before most of the public even knew what a Mac was. I suppose you'd say the same about those who choose to buy a popular mountain bike just because loads of riders like the bike, encouraging more to buy said bike, which they love, thus encouraging idiots like you to call them “sheep".
Regarding the 4G iPhone, it's guaranteed it'll be out in June, as was the 3Gs, the 3G, and the 2G. Apple work on a twelve-month update/release cycle for hardware. It'll almost certainly be a 64Gb capacity, probably with a 5Mp camera, possibly with the A4 processor used in the iPad. Probably double the RAM as well. It's quite probable that iOS4 will be released before then, as an upgrade for older phones and Touches, so that'll probably be on the 4G as well.
As my contract ends at the end of May, I'm looking forward to the increased capacity; my 16Gb 3G only has 665Mb left…
