While i agree with testj, i can see the point about all the crying about what the n800 can't do can be annoying when it does what Nokia advertised it would do out of the box. If people would do there homework before that buy things on the fly they'd know the limitations of the device before hand.
Now if it's just that their giving feed back on the product and how the device can be improved then that is different. Feed back maybe seen as crying when so many people are suggesting the same thing. I don't see why anyone should take offense when giving free information on how to or what would better their product.
As a consumer device if Nokia really wants to sell this product they 'd improve some of the limitations sooner than later. My 3 are:
1. A sync tool for calendar, contacts, and tasks with MS Outlook is a must but the n800 is meant to be coupled with a mobile phone and most mobile phones have tools to do this so why do it twice may have been their thinking. But the business consumer spends lots of money every year why not get them to do it twice by buying your mobile phone then buying the n800 as well?
2. Skype is not that important to me but i'd like to it see soon as a bonus and with webcam support if possible.
3. A2DP is very important to me and should have been supported from the jump in my opinion. Most mobile users have cut the cord with bluetooth headsets on their cell phones, and now having to go back to corded headphones for the n800 just sucks.

I know there are work a rounds for this and that if you like getting your hands dirty but their would be a much larger consumer base if the n800 had all the capabilities of a wm pda and more builtin but done better.
