I just got a "free" S2 8.0 on Air Miles Rewards about 2 weeks ago. No buyer's remorse here, lol. The only feature i would covet in the new S3 would be the 4 speakers. I am glad to see Samsung got rid of those two holes in the tab back used for the Samsung proprietary snap-in cases. I am currently using a great Fintie smart case, which is a simpler and cheaper solution. Sounds like the S3 is going to use magnets for cover attachment; Samsung always follows Apple, lol.
The S3 is currently not being offered in the smaller 8" size. I need something small and light. The S3 CPU performance increase is only incremental and would not make any difference for my everyday usage. Any increased battery life is always welcome, but i am already more than impressed with S2 battery performance. I definitely have no need for the S-pen and would not want to carry it. And I have never been a fan of glass backs, which would get covered by a case anyways. The glass has also made the S3 40-50 grams heavier than the S2. And it is back to up to 6mm thickness with only a marginal increase in battery size. And the projected S3 prices seem extremely high. I paid nothing for my S2. No way I would pay anything for an S3.
