The first impression that most people have of the Nokia E61 is that it looks just like a Blackberry. Teetering in between the realms of a smartphone and a PDA, the E61 runs off of the growing-in-popularity Symbian OS 9.1. The screen is a standard 240x320 landscape, more than adequate for your quick SMS and email needs. All the regular pre-requisites for a device of this nature are there as well, including WiFi, GPRS, EDGE, 3G connectivity, IR, a mini-SD expansion slot, and Bluetooth 1.2. What may be interesting to some though is that the E61 is lacking a camera, making it well placed as a device aimed at business use.
The unit is well-balanced and the build quality is good. The keyboard, placed below the screen as per usual, can be somewhat troublesome at times though the size and spacing of the keys results in a OKL sometimes when all you want is an K but considering that most people aren't going to be composing their memoirs on this thing, it'll do just fine.
Expect a Q2 2006 launch date for the E61. Price, as of yet, has not been announced.
