the E90 is the most powerful Nokia Communicator ever created. Two fully functional screens and one of them offering the fantastic 800x352 resolution, not only UMTS but also 3.6 Mbps HSDPA connectivity, quadband GSM, built-in GPS receiver, fast and powerful OMAP2420 processor running at 330 MHz, 128 MB of RAM memory with almost 80 MB available for the user and providing true and unlimited multitasking, very good 3.2 MPix camera with autofocus producing both great still pictures and TV-quality VGA resolution (640x480 pixels, 30 frames per second) videos, superb keyboard with perfectly shaped keys and very good tactile feedback, high quality materials and superb build quality, USB 2.0 and Bluetooth connectivity, stereo audio with A2DP support for stereo streaming over Bluetooth, good standby and talk times, very good size and tolerable weight, elegant and stylish design.... quite a lot of powerful features for a single device. Of course, one might complain about lack of 8 GB Microdrive like in the HTC Athena (weighing 360 g), no triband WCDMA providing worlwide UMTS support, 2.5" jack instead of the 3.5" one, no WLAN A support, etc., etc., etc. What I feel, however, is that the E90 is a truly poweful mobile device, definitely one of the most powerful PDA-phones ever created.
