Im a heavy user of rememberthemilk.com, the m.rememberthemilk.com site is a nice mobile version but is made for mobilephone. I did a first version of a greasemonkeyscript that makes it more fingerfriendly for the N800. If anyone is interested in it I add it here. Theres more to be done in it but this version makes it usefull..

to-install
1. download the zip,
2. unzip
3. put on tablet and click on it from the filemanager.
