Before my Galaxy S2 I owned (for about 3 weeks) a Samsung Infuse. My experience was pretty much what you describe: terrible GPS, 0 updates (that's mostly an AT&T issue though), slow as molasses... But the S2 is head and shoulders over it. Fastest phone I've ever used (yes, even faster than the iPhone 4S), the GPS precision was the best of all the devices we own at the company (we develop a product that requires GPS so we keep tabs on that), and the new version of TouchWiz is as good as anything else. Still, I'd love to have it updated to ICS at some point (and AT&T has promised they'd do it), but all in all it's a great Android phone.
