i see it a great phone
The thing about taking the joystick off is a good thing i realy think the w810 is better then k800i trying them bouth at the joystick area (w810) has normal buttons but realy better manevrable and not failing every 1-2 mounths =)
The camera ... i dont think someone whould need bigger photos in theyr phones ~800k-1000k is realy enough for a photo 5mp is a realy high resolution i hope pictures to look better, the video stuff will be allot better it would be good to be a vga video capture =)
The price is what i dont think i will spent ... the k800 does the job pretty well and its not so big difference, but maibe for a k750 user will be great :D
