Due to my relationship with Nokia over the years, I have more than a few of these devices in my desk drawer (N95, N82, E61i, E51, E90), but I always had more than a few gripes about them (too big, don't need multimedia or fancy camera, no qwerty keyboard) and tossed them in a drawer.
With the introduction of the E71, however, that might be about to change. Sure, there are a couple of small things about the device I don't like (i.e., the size of the keyboard or that it's a fingerprint magnet), but it has come closer to what business professionals need than any of the others, save the E90, and that was too large for me.
I'm a medical professional and I just wish that Skyscape and Epocrates would include the S60 platform in their arsenal of products. It's the one glaring reason I keep returning to Windows Mobile, no shortage of medical software. While I'm testing this device out, I'll have to go back to writing prescriptions by hand and using actual books for medical reference.
But I have to say that this device is a darn good start.
