I've had my new Nokia N810 for just over one week. It's the gadget in the bottom right of the picture, also shown are a HP calculator from 1985 (which I still use but it lives in my desk drawer) a Palm IIIe and last year's Nokia N800. So what's it like? Well a colleague who owns a N800 described it as "techie bling", which is what HP calculators were in the 1980s, so it's probably a fair description.
Initial impressions are that the keys on the keyboard are too small, the miniSD memory slot is too fiddly, the keys on the top are very hard to find with the keyboard open and the display quality much better than the N800. The built in GPS is interesting, and I'm bound to find uses for it.
