So I have a iPhone 4S 16GB right now and I'm looking to upgrade to a iPhone 6. I have just over 2GB of free space on my 4S but only cause I deleted a few videos off the phone. I really wish Apple had gone with 32GB for the base model but since they did not do so do you think it's worth it to go for the 64GB model?? Also I'm torn between the white/silver and black/space grey. They both look good and either way I'd likely get the black Apple leather case. I know it's ultimately my choice but which have you guys picked and why?
