The N800 lacks a certain level of polish compared to WinMo. The MS platform delivers good business connectivity for word, excel and outlook email. The negatives are the stability issues that another user talked about and the browser options are terrible.
For using word docs on N800 try this workaround , Gnumeric is good for spreadsheets.
For email use I tried using Claws Mail for a while which is a great IMAP client but I found that using Exchange Web Access was a lot better and the screen fits excellently on the 800 pixel wide screen.
Basically if you want to use web based tools for connectivity the N800 is great if you want to sync for offline use then the Windows Mobile unit is probably a better bet.

The 2.2.7 version of abiword WITH the
more-gconv-modules works reasonably well- it
will save as an .rtf (although it has a .doc
extension), and it will handle reasonable tasks
(although notably not bullets and numbered lists).
I would consider it an alpha product, leaning
toward beta. Gnumeric is solid as a rock, though,
and handles .xls without complaint. Hope that helps. K.ps. K.ps.

PocketPC is an HP12C calculator

The Nokia N800 is an Apple II

Your choice

What about online text editor programs like Google Docs and Spreadsheet, has anyone tried this apps. looking though you have to be online for Google's editor to work.

I have not had any problems with SciTE for word documents and gnumeric for excel they both work grate.... And for emailing I use claws-email.. simply the best
I use this tools quite often since I am in the field a lot.

Thank you all for your advise, I don't think the N800 is a mature enough device for my needs. The Strong Text editor is my major concern. Thank you again and I will be looking at the next generation Nokia Tablet, a Pocket PC lasts about three years, the way I use them.

Thanks, I'll check it out!

You don't know how much better this is, on devices like this its akin to going from a 27" TV to a 42" TV!

I've got the 770 which is a little bit smaller then the N800, but the size has never been an issue for me.

This is a great feature that makes answering email with out a BT keyboard a much more pleasant exercise. I'm very happy with the touchscreen keyboard, I'm surprise more devices don't use such a concept.

Maemo Mapper is an awesome navigation program that's free. I use it with a $70 Rikaline GPS that holds a GPS signal better then some purpose built GPS'! 90% of the time the app serves my purpose, the only time if fails is when you need to make a change to itinerary and without an Internet connection that can pose a problem, but for me at least, that doesn't happen that often.

rdesktop and vnc are available, don't recall is the PocketPC has both apps available.

One area that lacks a little on the N800, but if you don't need editing capabilities, I've had great luck with converting my excel and word docs to PDF and using them on the IT. http://www.expresspdf.com/

My experiences has been that IrDA is slowing dying out as connectivity option being replaced by BT.
