The Nokia N810 was launched this week, and among the main details, I've got a few more impressions for you. (What few impressions I could draw from the quirky device.)
• Screen is A+ in sharpness, color, brightness and res (800x480). It's not multitouch, though, and you'll need a stylus.
• The keyboard's clicks are a bit shallow and the space between each is not so well defined, but it is something you could get used to.
• The Linux apps were not readily available yet, and some.
• An app I missed in my video walkthrough is that Gizmo has video conferencing support using the front-mounted cam. (And there is no app for using it to take straight- up photos.)
• Would I buy it? I'm not sure I need it. But the dev community for Nokia tablets is pretty popular (although not as popular as s60) so I'm sure there are untold uses for many inside of this thing.
• When WiMax hits, an upgraded device like this could be very useful. Right now, it's a Wi-Fi or tethered over Bluetooth device.
One huge benefit of the N810 over the iPod Touch (and iPhone, by extension) is that the N810 will work with any of the major desktop operating systems. Apple's hardware is locked down to iTunes and iTunes is not available for any flavor of unix except OSX.
In addition, I travel from time to time but don't really enjoy lugging my laptop through airport security, taxis, trains, etc. With the N810, I can still load SSH or VNC and take care of any server emergencies from afar. I can check my email, find local eateries, and use the GPS to mark my way. I can tether the N810 to my 3G phone and surf faster than any iPhone. And with my removable sim card, I can surf cheaply in London or anywhere else that supports GSM. The little beastie will play movies for me, enough to fill up a flight to Auckland from Florida, provided I bring a couple 8G SD cards.
The iPhone has a finger-friendly UI that beats the pants off of, well, everything. It also is self-contained, so unlike the N810, it doesn't require a phone to surf the cell networks. It is also a bit smaller, which makes it easier to drop into a pocket.
But if you want to avoid the MS and Apple walled gardens, the Nokia N810 is a capable and friendly device.
