Funny, I gave mine away yesterday. But to a hacker who will use it in contrast to me; I've barely used it past months. Nokia got my money for their excellent Nokia E71 which partly replaced my Nokia N810, and I will probably buy the new Maemo 5 device to use as 'nettop'. I'm very excited about Maemo 5 and RX-51, but not about Nokia N8x0 and Maemo 4.x anymore even though there is going to be vibrant community support it just is not practical for me as is.

There are some nice mods for N810 like Mugen 3600 mAh, full SD, accelerometer. Its a fun device to play with, but IMO not for serious usage. Debian and Mer should work on x86 as well, and with SB2 you can easily then use this on the NIT to port software and hack on it. So it can be really a lot of fun, and if you liked the N800 and want more relatively similar experience then N810 is nice. Both have their strong and weak points; therefore I see them as complimenting as well.

If you ordered from Amazon.de you'll also get the correct QWERTZ layout and charger. You'll probably love the included stylus and later enjoy backports from Maemo 5 to this device a lot. All in all, with a price drop of 100 EUR (33%), why not? Just, I think the price will soon fall even more.
