Haha, I hope my comments about the S5 point out that I'm not a Samsung fan. As a matter of fact I've been at least a few from that list, if not most at some point.
Actually fanboys are all jerking off to that phone, saying how it's the best looking one and how Sony has the best design. The bezels are ugly and the phone is literally a rectangle. It's not terrible imho, but not great at all. And Sony still need to do something about their displays which are the worst of all companies, which is a shame considering Sony's TV reputation and how they're boasting gazillion of display techs whenever their new phone is coming out.
They're good because they're GSM. GSM is good, CDMA is not. I don't really understand why so many people in the US (because nobody else uses CDMA) tolerates carriers using CDMA. Compared to GSM it's just limiting so badly. Also, phones are not designed for CDMA - they're designed for GSM and the fact manufacturers and radio manufacturers have to consider a CDMA variant means more costs to them and the hardware for CMDA is never as polished.

Technically Retina on new Ipads is 2K. 2K means resolution in any form factor with the vertical (or horizontal depending on which is the bigger) resolution higher than 2000 pixels. With displays, 2K usually means QHD which is higher than retina, however - since for instance the 2K Samsung tablets have a 2560x1600 resolution.
Unfortunately tick-tock is the philosophy Intel applied, but nobody else. The S4 was a much bigger upgrade compared to the S5 and pushed the technology much futher. The S5 was the tiniest update possible on many fields but then again the smartphone tech seems to be stalling - everyone hoped Samsung would push it forward. Now all eyes are on Apple since they seem to be designing their phones regardless of what the rest of the market is doing and might come up with something interesting.
If I had the S3 now and was considering an upgrade and my upgrade was due this fall or a faster one in April I'd wait for the proper one this fall - the new LG G3 will be out, the Note 4 will be out and the new Nexus phone will be out. The Snapdragon 805 will be out and maybe the Tegra K1 will be out.
There was a bigger jump last year, so far this year not much has changed from the last year.
If I was buying a phone soon I'd get the LG G2, Note 3 or the Nexus 5 despite the S5 being out (although let's wait for the reviews).
