As a writer, this is important for me to know, since if they aren't worth the money to purchase (and many of them are indeed for-pay, rather than Open Source), I need to avoid mistakes. Currently looking at several programs, some of which I know are likely to be Windows-only. Since I currently use Linux (in the form of Linux Mint 10) rather heavily since it is much easier on my battery, this could be an issue. Pity I cannot recall the names of specific ones at this moment which is highly annoying, but will search my computer for data files saved from various trialware. Okay. This is truly annoying. I know I have data stored on this machine from such programs, but no joy on finding the titles ATM.
