Well lets hope Sony isn't one to cheap out since they are sorta audio focused. Thanks for the advice. I was looking at the U3 cards, but I think I can safely lower my expenditure to the U1 cards. Not a lot of options for 128GB at U3 anyway.

My 2 cents...

Removable battery: do you expect to actually swap batteries? I got the G3 and have yet to be in a situation where I actually need to swap battery, some of that has to do with my use habits, but still, with decent battery life, and regular (daily) charging, it hasn't been an issue.

SD Card: How much do you think you will use the SD card? The big data chunks by my analysis are photo/video and music. Photo/video can be EASILY put into the clouds now (google photo = holy shit), but audio is a mixed bag. Will you use your phone as audio source, or do you have a dedicated player? If you are not using phone as audio source, then SD storage, while really nice, becomes less essential.

Fingerprint ID: I miss this SO MUCH from my 5s. Enough that I still haven't sold my 5s, because (along with things like size difference, certain UI preferences, etc) I might switch back for now. Even with knock code, and all the other cool ways to get into your phone, touch/fingerprint id is tremendously convenient. I thought I wouldn't care, but after switching away from having it, it is not a trivial feature.

The G3 is a very nice phone (for my uses) and the G4 improves on that, but it seems like you are leaning toward the S6. My suggestion: if you have no strong feelings about the UI overlays, and don't use your phone as a source, go with the S6.

I've always used my phone as a car music player in the past,  which makes microSD cards a fairly big deal to me.  I like the removable battery only under the off-chance that mine craps out on me.

But maybe I just get a cheap fiio and move on.

I'm a bit worried about the all glass construction of the s6 as well.  A fingerprint magnet if nothing else.

But,  the s6 is sleeker and I really am not a fan of big phones.  Plus,  the fingerprint scanner like I mentioned.  I've been enjoying my tab s quite a bit.

Edge was kind of cool when I got to play with it at CES. Question is can you switch from iOS to Android without flipping out?

Should be okay! iPhone 5 was my first Apple phone so I'm not in the deeply entrenched category yet. Edge looked like a neat alternative to getting a 6, reviews are a bit scarce but I figure ZD and others might have gotten some play time with it already.

Why the Edge, specifically, over the regular GS6? I still fail to see anything useful about it at all.
