IMO the bloatware in Samsung phones (or LG phones, etc) is NOT the reason for the lag or worse memory management.
It's the optimization. IOS also has "bloatware" (apps like magazine, ibooks, stocks, watch apps, etc) but hasn't got that much lag or whatever.
It's all in the optimisation.
People can disable all the bloatware they want. It won't truly matter. Same happens with custom roms without the bloat. They aren't faster or better at memory management.
100% this.
I really don't even care about the extra Samsung apps or whatever bloatware, especially if you can disable and make them more or less disappear. That's more than you can say about Apple's bloatware on iOS, where you have to just relegate them to an "Apple Extras" folder (that's what I do on my 6). Every device has some bloatware to some degree, even stock Android, because it all depends on what apps the user wants to use.
The key is the optimization and memory management as mentioned here. And if TouchWiz is as optimized as Samsung promises, then I don't think there will be any problems. Reviews have all said TW is scaled back, less intrusive, less obvious, and optimized to the point of smooth as butter.
Looks promising. I'm not overly worried anymore about TW as much as I was a week ago.
Like I said in an earlier post, the biggest knock, I think, one can make against the S6 is the step back in battery life when comparing to the S5. But if it's rating slightly better than the iPh6, and given its Quick Charge/Wireless charging, and it's battery saving modes, I think I'll be just fine.

Does Samsung actually sell unlocked, carrier free phones in the US? Save for the GPE S4, I don't recall being able to get completely unlocked phones as you could with HTC's unlocked or developer versions, or Moto'x unlocked versions of the X.
I'm not sure. This is the first Samsung device I've ever been seriously interested in. That would be unfortunate if they don't though! Everyone does, even Apple eventually. It would be a shame if Samsung didn't.
Does anybody know more definitively whether they'll sell unlocked devices? Maybe on their website?
