I won't be tethering it, but I honestly don't feel the need (nor do I wish to pay for the data plan). I have wi-fi in the house, at work, at hotels, etc. That's not the issue.

Can anyone answer the memory question? Is the n800 totally SDHC compliant? Are there 16GB cards available?

Also, what about the apps? I assume there are text editors and spreadsheets for the n800, but I don't know what they are.
