A little review from a real person. I read this on another tech forum. His initials A.H.
Had a good 30 minutes playing around with the S6 and Edge at the Samsung Experience store in Central London. I went there with high hopes, haven't owned anything Samsung since the S3, but I was surprised by how completely underwhelmed I was. Don't get me wrong, the screens are off the charts great, as is the camera, but the Edge didn't feel nice in hand at all. Neither had the heft or feel that screams premium(and that was expense of worse batttery life than the S5 as fully reviewed in GSM Arena!). UX is much improved, but it's still bloody Touchwizz which feels as slow as walking through treacle compared to Stock or Sense. I just don't think the beautiful screen and the camera is enough for me to compromise for losing battery life, putting up with crap mono speaker, Touchwizz. Maybe I'll wait for the Note 5 Edge or G4.
I don't take any issue with non-removable batteries because, as long as they are good quality lithium-polymer, SOCs are good enough now to get through at least a day. What I do absolutely take issue with, is making a phone thinner by 0.1 to try compete with iphone 6, at the expense of extra battery, when it is a complete non-issue to everyone except Jony Ive. Android users would happily take extra battery life for the sake of 1-2mm thickness 100%.
I'm not completely happy about the loss of SD slot. I use cloud services as little as possible, and certainly wouldn't touch anything Microsoft, and I would at least like the choice. Both options are very cheap, I don't know why OEMs get away with charging premiums for it. Besides, any tinkerers out there prefer an SD for flashing ROMs etc, whenever possible, which is actually one of the reasons Google/OEMs are happy to see it go...Good for them to remove choices, bad for consumers...
