I think either the onscreen keyboard of the n800 and the hardware keyboard of the n810 is going to be about the same in terms of typing speed. The onscreen finger keyboard works pretty good. Here's a picture of the onscreen keyboard, http://www.pocketables.net/2007/08/review-nokia-n8.html . It is very useable. I don't agree with the comments of the reviewer. Also regarding the touchsceen smudges/durability, just use a screen protector.

I think you need to decide if you want the capability of having 32 gb of storage. The n810 is limited to 2g plus whatever the largest miniSD card is. I think its 8 gb. N800 = cheap 32 gb capacity versus N810 = expensive 10 gb capacity. I really like the N800 and its cheaper. The N810 is plastic so its not going to have as solid a feel to it. I like the all metal construction of the N800 case and it is a pretty solid unit, no sliding keyboard to weaken the construction. The other thing is that SDHC cards are cheap and abundant. The 32 gb SDHC cards that are coming out will be cheaper than any equivalent miniSDHC cards.

If you want to have power keyboard input, get a bluetooth keyboard. I also think the bluetooth GPS's have better sensitivity that the built in one on the N810. For the same amount of cash for you new N810 with wimax you can get a N800 with 32 gb of SDHC cards. You won't be able to carry around that amount of storage on your N810 plus you won't need to take your mp3 player with you so you'll have less stuff to lug around. The N800 would be your one stop shop for most of your needs. My N800 because of the high capacity SD cards is my portable library, entertainment center, computer, skype phone, etc.. It was an easy decision to go with the N800 over the N810 just based on the SDHC card format. It really depends on how much you want to push the envelop of what the unit can do, but the N800's dual SDHC cards is a big capability especially in light of the cost differential and availability of cards. SDHC has larger and cheaper $/gb cost than miniSD plus you have an additional card slot in the N800. New models may not be better than older models especially since you will have basically the same computing power when you install OS2008 on the N800.

On my internal 16 gb card I have KDE, wikipedia (yup entire searchable text version of wikipedia in Sdict dictionary), entire webster's collegiate dictionary, german english dictionary, and 5 other dictionaries and thesauruses, 10 gb of music, another 1 gb of storage, 1 gb of ebooks. Then I have another 15 gb of music and movies on my external SD slot. The N800 is really pumped up with alot of goodies because I have 32 gb of storage. I also have another 4 x 16 gb of storage and media. I have a total of 6 x 16 gb of storage (96 gb) because the N800 can use SDHC. This thing has more storage than a Sony UX computer and at 1/2 the cost ($182 for N800 plus 6 x $65 per 16 gb SDHC = $572). It sounds alot for the SDHC cards, but the N800 is my 8 oz. UMPC solution with alot of free software. Just Sdict alone will impress you as to what you can lug around in 8 oz. device. I think have the ability to store and retrieve off line data on the SDHC cards is a capability that you might not want to underestimate.

www.gutenberg.org has alot of free ebooks. If you are traveling and don't have access to internet, the ability to have off line content is nice. I expect to not have wifi access when traveling so I have an extensive amount of entertainment amusements. Having cheap storage allows you to take whatever you please. Also the SDHC will give me a cheap photobank which is solid state.
