I've only ever owned one Sam and it was the 2nd worst POS I ever had. To be fair, Sam's hv gotten better since that time but I wouldn't want to risk it again. In contrast, I've owned 2 SE's (incl the w810), loved them both and still have them. This is even tho the older one doesn't have 850Mhz (backup). Yes the keys are smaller, but the interface is more user friendly and you'll find that once you're used to the smaller keys you'll be very quick with the phone. The other thing that I find, the SE is easier for me to use one-handed (for txt etc...) than my old Moto. Plus a few more options for modding, aftermarket, etc...
