Vim is the editor I use almost exclusively. Under RISC OS, Windows or Linux. Lots of neat features. I especially recommend its macro system (for complicated editing of lots of lines in one go), and vimdiff.

Shareware / trialware

Some really good shareware / trialware I've purchased throughout the years.

- Go here for ACDSee. A very good image viewer/processor for PCs.
- Go here for Agent. A well thought out email program and news reader.
- Go here for Spheres of Chaos, a great looking, really addictive 'Indie' game.
