After a bit of time with the Nokia N810

The Nokia N810 is the third product in the Internet Tablet lineup from the Finnish handset manufacturer. Featuring a large 4.1" touchscreen with 800x480 pixel resolution and based on Maemo, a Linux based user interface, Nokia's Internet Tablets are slowly progressing from a geek toy to a consumer device.
With the N810, Nokia has added a slide-out QWERTY keyboard and a built-in GPS receiver. Nokia also stuffed 2GB of built-in memory inside, with a miniSD card slot for expanded storage. The N810 retains many of the hardware features of the N800, such as a built-in VGA resolution camera for video calling, hardware buttons for zooming in and out on the interface, and a 3.5mm audio jack. The N810 uses a micro-USB port for data transfer and also sports a built-in kickstand for convenience.
With the N810, Maemo also got updated to Tablet OS2008, code named 'Chinook'. This new version adds quite a bit of eye candy, with semi-transparent menus and home screen applets, as well as a more finger-friendly menu system. Updated Flash means that YouTube videos play easily in the new Mozilla-based browser, as well.
The Nokia N810 with OS2008 also features an updated Gizmo Project client, which allows you to use the tablet as a VOIP phone, and also supports tablet-to-PC video calling. An internet radio directory is also included, so users can easily use the Nokia N810 as a portable Internet radio player. The N810's processor runs at a speedy 400MHz, which keeps the menus snappy.

The slide-out QWERTY keyboard on the Nokia N810 is a welcome addition, and offers much quicker text input versus the N800's on-screen virtual keyboard options. The top row of keys, however, are a bit difficult to reach, since the bottom edge of the top sliding portion stops right above them. Otherwise, the in-hand feel of the device on a whole is simply phenomenal. The N810 feels rock solid, and the new smooth aluminum faceplate adds greatly to tablet's looks. The N810 is overall thinner than its predecessors, measuring 128mm x 72mm x 14mm (5" x 3" x .55"), though it is still well balanced enough so as to be comfortable to use.
The N810 features stereo speakers, located on the sides of the device, which unfortunately directs the sound away from instead of towards the user. Included in the sales packaging is a new dashboard mount, so that the Nokia N810 can function as an in-car GPS solution. Wayfinder mapping software is included with user-downloadable maps, though navigation is a paid upgrade.
