Welllll...normal free skype is comp to comp....and instead of just perpetually putting money into your account to call friends....I suggest spending the 30$ a yr for unlimited North America wide....or around 100$ a yr for unlimited Worldwide....then you can not only call computers, but cell and homephone numbers too. Great in a pinch..with skypeout ....yup you can call your buds ...if you are lucky enough to live in an area that enables a skypein phone# even better....that means you can receive PHONE calls or have em go to voice mail...for about 10 or so bucks a month...I think...may be a little more or less.......

BTW.....should check out the solio with the 3 cell fold out...works great with n800....cheap on ebay too....built in battery holds a full charge for a yr. and can charge a n800 from an exhausted battery state...and it solar charges ...best to suction-cup-it to a (car)window or stand it up...and fully charged solio hooked up to a fully charged n800 running during the day means that even though you are draining the solio battery it is also charging off sun/day light during use...then after a day of use with daylight diminishing it starts draining the solio battery to feed the n800 battery and finally you are running on n800 battery alone...looong playtime ...and you can charge the solio via usb quick too in a pinch to ready for emergency or travel prep......been around for yrs. I got 2 ....work great...So say power goes out...calamity strikes...its all good...you got music, movies, books, games, and connectivity...while everyone else is still sitting in the dark.

You can also vidchat with the n800

And gps ..yup
THESE are the least of the things you can do with it.

rdesktop..check it out.....REMOTE computer access

MULTIPLE...as in many options of Operating Systems
Best...other than maemo... is Easy Debian...you can play with nitdroid (Nokia Internet Tablet Android OS)
And lotsa others.

Lilo...one of (many) the most important thing to remember is this.
The Maemo operating system and the devices n770/n800/n810/n900 and the software was handed by Nokia over to OUR community....No corp. controls us anymore ...this means that we maintain the stuff....enhance...write programs...etc. We help one another. If software becomes screwwy with the ever changing internet....community members work on fixes....not like corps that tend to start abandoning device support not long after they release it.
