With all due respect (just kidding
)
All seriousness aside, before trying calibre, I looked high and low for a program that would do what calibre does for me. While many of them had some really nice interfaces without unnecessary bells and whistles, none were able to do as much for me a calibre. And most didn't have a forum like this. While I do like an attractive, showy interface, in the end, I'll take functionality over glitz any day of the week (especially the ones with an "a" in them). Of course, there are the ones that were written by geeks for geeks (geek is not a derogatory term here; quite the opposite actually) that are totally over my head. Kovid has done a pretty good job of appealing to both geeks and users like me who only know enough about computers to get into serious trouble (thank God for forums like this one to bail me out!).
