Nice read Del, it's really hard to make a comparison if you've missed out on device upgrades. I didn't have the opportunity to move to the s3, so trying to figure out what the s4 has that my s2 doesn't is really not practical. I mean that by saying that I'm sure there are so many differences that the comparison would be inappropriate
I just have to add the following: The feature apps on the S4 will be made available for the SIII and the Note 2. That´s a given. It will be bundled with the next OS update to 4.2.2 according to the rep that handed me the S4.
I forgot to ask if the eye-trackimg and gestures will also be implemented, given that there´s no specific hardware needed, instead it´s just software that takes care of this.
So, as far as I can see, yeah, the S4 is a little better (faster essentially) than the SIII. The size of the smartphone is almost not noticeable. The plastics, of a different hue, seem of better quality. Glenn will understand the difference, you had the Note 2. The plastics are the same. It just looks better than the S3, but not by much.
As far as the UI, also yes. But very slight. Not really my cup of tea ...
I think this phone is amazing and it's going to sell well I'm sure. I have on my GS3 4.2.2 as I'm rooted running Paranoid Android Rom and already using all the features of the SG4. Good review Delfim and I agree with you on it. B-)
