I have Nokia E71 but I need a Windows Mobile-based handset. Will going for the Samsung i780 be a good choice? I need it to work like the Nokia E71.
You are essentially looking at two different operating systems with the Nokia E71 and the Samsung SGH-i780. The E71 runs on the Symbian S60 software, while the SGH-i780 is based on Windows Mobile 6.1 Professional. The user interface is very different for both smart phones, not to mention the SGH-i780 has a touchscreen LCD and the E71 doesn't. You may want to refer to our quick guide to handheld OS here.
In a nutshell, if you want the same handling (not referring to features) as the E71, it's best to stick to a Symbian S60 device as the user interface is generally consistent throughout different handsets, even for other makes. Alternatively, if you are looking for a QWERTY device, here are our suggestions.
