What you are asking is the essence begining Linux. With the Xterminal you have at your finger tips the fpower of an fully operational battle station, er, I mean Linux computer. One thing that most people don't realize is that that *NIX is *NIX is *NIX. Different Unixs are a lot more alike then they are different. The basic Unix things I learned, (ye gads) almost 30 years again on high end Unix box are still applicable to the small N900. The same commands I run on the big IBM AIX hardware at work are the same I used on my Linux desktops which is the same on the N900.

When everyone says go get a beginning Linux user docs, that's your begninng N900 Xterminal tutorial. 80% of what pick up from there is directly applicable to the N900. The N900 IS a Linux computer. 'Linux for Dummies' can be subtitled 'N900 Xterm for Dummies'.
