The 8000 was a creaky mess. I supported 1000s of them and they all creaked esp the battery cover.
I guess we're embarrassed by different things... I like my iPhone a lot but still miss my BlackBerry from time to time.... They had the best integration and smartphone experience up until the iPhone. Their always-on connectivity is something Apple built off of.... Jobs even described the iPhone's push email features as being "same as a BlackBerry"... they were the industry standard.
Agree they're no longer relevant but I have a soft spot for the huge contribution they made.
I think the main reason they lost relevance is the same reason they were successful... they defined their product around a particular set of users... primarily business folks. I know it was a huge help for me while on long trips/in taxis to have email integrated as well as it was... I appreciated their dedication to my user experience, and not cluttering it with unnecessary distractions.... I still miss my physical keyboard!
One more thing: Before the iPhone I contend that BB had the most beautiful smartphones.

Don't think there was anything close to that design/detail out there at the time.
