IT started this spring when I started playing around with OpenOffice, mainly because I wanted a program that would also convert files to PDF. Now I do much of my writing in it rather than MSOffice (as much as possible anyway).
THen on the weekend I was having trouble opening blogs. True the fault lay with SIteMEter not IE but still it prompted me to download FireFox and once looking at it I changed it to my default browser.
Then I decided to go all the way and change my e-mail client to Thunderbird.
Now I am not about to change to a Linux operating system. But at least I am moving away from total reliance on the products of Bill GAtes et al.
