I've been using yahoo for 14 years, and I hate gmail. I do have a gmail account because I need it for my droid. I like the gmail app (I use it as a secondary email at work when I'm out of office or after hours), but I don't want to quit using my yahoo mail account because I've had it for so long, and a lot of old contacts still have it and use it occasionally.
Yahoo, please develop an app for android!
