microsoft office

I've been using computers for well over 20 years and have used a lot of different programs and at the end of the day; the package that works best for me is microsoft office. Although there are other office packages that are similar to microsoft office, the differences between microsoft office and the other programs are what I don't like. I guess the reason I like microsoft office so much is that I am proficient in it, but not in other programs. Of course at the same time, since those are so close to microsoft office, I guess I could transfer that knowledge to the other programs, making me proficient in them.

It's funny, for as much as I like microsoft office, I've tried the newest version and don't like the interface. I can't help it but I like the classic look and interface better than the new look. I know I'm being picky about it but what can I say? If the interface looks different and I can't easily find what I need then it bugs me to no end.
