Aaah, my first ever owned mobile phone! Not too fond of it, though. Big, bulky and expensive, I was eager to replace it with a smaller and more efficient device. The calls were expensive too and the phone's battery life was terrible (good riddance, NiMH) so my first phone was used mostly for bragging rights... although I was what you would call a late adopter - the first mobile phones were commercially available in my country since 1997.
This was my first android phone and it was okay at the time, but like with most slider phones, it had the issue where the ribbon cable would get worn out and the screen would get glitchy. This was fixed by myself by replacing the ribbon cable.
This phone has incredible build quality and is blazing fast. It has excellent development on XDA for added performance/function. Very few phones can compete with this when it comes to price to performance ratio.
