I had some pieces at the beginning, but they weren't disappointing at the time, like the Qualcomms and the first generation Sanyos...At the time they worked as good as anything out, we just didn't knowwhat was coming!
My worst phone was my first BB: 7100t on IDEN...That made me swear off BBs for a LONG time! I was surprised when I tried the Pearl (of believe me- I made VERY sure there was an option to return!)
RIM has come a long way in a few years though, the new generations of BBs are very good, and I love my pearl. I suppose I'll upgrade to a curve or something when it dies, but for now I'm more than satisifed. And my husband would never have owned a "smartphone", but I don't think he could live without his curve now...
