for me the s5 was a hesitant buy, it was a fairly decent upgrade on the S3 but not the S4, I had an S3. However I was still on the fence as there were rumours that the prime would follow. I then decided to wait but shortly after Samsung's CEO stated categorically there would be no prime, so I bought the S5
No, my S5 wont suddenly loose its potency as soon as the S5 prime comes out, I wont even care the S5 is not the top phone anymore, its that this new phone is going to be a lot better and I bet it will be much more on contract than the S5, therefore I would have had a far superior phone if I had just waited a while longer.
Given the choice I would have waited, I dont like being lied too either, this is why I have a problem, thought more people would fee the same way, obviously not.
