I did a search on Google for "Perfect Phone" and this is what I got:

Along with many people just wish they had gone to 4GB of RAM. But I'm sure even then we would leave so many applications open that it wouldn't make a difference and likely drain the awesome battery life. I really enjoy my S5 and I have had it since launch.
Don't hesitate, it is the best phone out there for the next 2 weeks... until something more expensive and awesome comes out. /technology
