Asus eee pc (linux)

I acquired an old eee pc 4g recently. Needed some bits, which I have now sourced.
However, I couldn't get it to connect to my talktalk wireless broadband. :(

The problem appears to be the WPA2 encryption on the router. It works fine for the MSI netbook, and even the allfine wince (ouch) machine. But not the eee pc.

The solution appears to be a BIOS update, available from ASUS, which will require using the wired connection. Which DOES work, I've tried it. However, I stupidly tried the "update software" icon on the desktop, and now all updates are greyed-out.

A bit of digging later, I found LOADS of useful info on the web. Going to try manually updating the machine, and I don't expect too much bother.

All I need then are filezilla (which I KNOW is available for eee pcc, and a source code editor in the style of crimson editor. Unfortunately, not available on Linux.. Any suggestions, anyone?

Talking to one of my (day-job) colleagues, I discovered that he used two eee pcs (Windows) to run the entire musical performance at a recent charity event, both machines running the fulll version of Sibelius! Impressive..
Apparently, FOUR people asked where the "orchestra" were.. :)
They even had a conductor, conducting the eee pcs.... classic.
