When my SE G900 suddenly bogged back 7 months, I needed to have a replacement phone fast and at that time I really don't know what to buy and I didn't wanna spend much on a phone that time. I wanted the E72 but it seemed that a lot of owners had problems with it. To cut the story short, I ended up buying the E63. It was less than 10k at CMK Cell shop. Up to now it's still not showing in signs of slowing or hanging. I'm not sure coz I use my phone for call and text only and flashlight.hehe Not really the best in its class though.
