Here's YAAIN (Yet Another Apple iPod nano) review. This time it's written by the guys from PC World. Anyway here's a short snip:

The first thing you notice about the flash-based iPod Nano, of course, is its tiny size. But what's really impressive about the Nano--and represents a breakthrough for the category of lilliputian MP3 players--is its bright, crisp color display, which makes navigating your tunes a snap.The slim Nano costs $249 for the 4GB version; a 2GB model sells for $199. It weighs 1.5 ounces and is about 0.25 inch thick--so small that you scarcely feel it when you have the Nano in your shirt pocket. Surprisingly, its size was no impediment to functionality: I navigated the Nano's menus, displayed on its barely-larger-than-a-postage-stamp display, without difficulty. The unit's screen resolution is sufficiently high that it can fit as many as 27 characters across, in extremely readable type..
