Hello, I just returned my S4 via FedEx to MetroPCS. I just can't fathom $600. Well, $550 after rebate as tax was $50, but it's still a lot of money. Now, the S3 is $350 after rebate, so $400 now, which is $150-200 cheaper than the S4. The S4 was a great phone, but the extra money to me doesn't justify the extra features. Yes, the smart features were cool, but will I use them? Probably not. The camera was pretty good, but it was default at 9.6MP(16:9) while the 13MP mode was only 4:3. I would of probably stuck with the 9.6MP(16:9). Now, the S3 has a 8MP camera which also does 1080P HD recording which to me is more than enough, and it looks like the S3 has more internal space available to the user than the S4. The S3 has a 1.5Ghz Dual Core while the S4 has a 1.9Ghz Quad Core. I really don't think I would feel the difference between the two as I would never be doing anything that would require 4 cores. The S3's 1.5Ghz Dual Core is most likely still pretty darn fast. The S3 still packs a good punch for sure, and I think a black phone would make me happier over a white phone too. I won't be doing anything until I receive my refund from MetroPCS, but I'm most likely going with the S3. If it wasn't the S3, it would be the LG F3, the LG F6, or the Samsung Galaxy Exhibit, but out of those 3, I rather the S3 for sure. I'm excited to be part of the S3 team.
