True. From reading posts it sounds like a lot of people would've preferred a whole new redesign of the phone with no real performance upgrades rather than the incremental upgrades of internal hardware.
I'm ashamed to say I'm one of those people! 😀 I'm sure if I had a 1st-gen phone, I would want to upgrade, but the differences between the 3G and 3GS are so minor (for my purposes) that I won't bother. I'm not looking to shoot masterpieces with my cellphone camera or video recorder, and the speed is fine right now for the kinds of things I do. The only really attractive new feature to me is the voice control, but considering that I don't like looking like I'm talking to myself in public, I'd probably use it for a few days, then get bored with it.
