Yep. I just replaced my N80 (another symbian phone) by an E51 (European version) and I am very pleased. Very stable and fast, good built-in browser, E-mail client works, and works very well with y N810. Also: I don't know about the US version, but the European version supports HSDPA, which bumps UMTS speed from 320K to 3,4Mbits/s...
