It always gets me when someone rants about 'fragmentation' and then mentions Windows as if it isn't an example of it. It's the BEST example of it. They forget how many versions of Windows there are, and how hard it used to be to get programs to work on different hardware, even though Windows itself was the same exact version.
I've actually been trying to reduce my web browser usage on my laptop and move what I can to local apps. I feel a lot safer using a Twitter app, than using Twitter in a web browser, and a lot safer using an IMAP client than a webmail client.
