I really must take issue with the statement "you can finally run a decent text editor on it.", as a long time RISCOS and MacOS user (there is an A9Home on the desk next to me, and a Core Duo iMac on my desk, so I can compare the two side by side), I know the editors on both platforms very well.
If you have ever used TextWrangler (free!), BBEdit, TextMate, Xcode, or almost any other text editor or IDE on the Mac, you will find them to be in a totally different class to StrongEd and Zap in every way, unicode support, code completion, folding, CVS/Subversion support is only the beginning. Xcode isn't even intended to be a standalone editor, but it's superior to anything on RISC OS (or Windows, for that matter).
I hate to rant on about this, but the longer us RISCOS users kid ourselves that certain software is comparable to Mac/Windows offerings, the worse the software situation will become. I could start banging on about Artworks Vs Illustrator/Freehand/Fireworks, but that's a discussion for another day...
