I my opnion, Galaxy SL for 19K is certainly better than both Defy and Wave II. Biggest screen, highest internal memory, slightly lesser ram than defy but slightly lesser pixels to crunch too, best battery(dont know abt back up).
Camera for a phone is just a bonus, its never a deciding factor. I mean cummon.. Galaxy S had the same camera, no one stops himself from buying one because of the lack of flash!!!
The screen in gsmarena shows SCLCD... I have seen the wave II screen and its certainly superior to the other LCD offerings around...
I only hope that this pushes the Defy pricing down, cause for me, i am still slightly tilted towards defy cause of the compact size and design. It seemed a lot better build than sansung galaxy 3, pop and 551.(Sadly Ace was out of stock at Croma this weekend, couldnt compare them
).
In all if anything deters anyone from buying SL would be its huge dimensions and all plastic built. Otherwise, its a game changing deal IMO.
