I personally wouldn't have - but I have two contract upgrades this month and had to do something with them (got my S2 on a 12-month contract last year). As mentioned, I think the S3 is a lot more incremental upgrade than the S2 was, and not really any single compelling reason to get one if you already have an S2.

If you're on an S1 or other device of the same generation, then of course the difference will be much much bigger.
