RIM is behind the curve right now (I'm talking from what consumers want point of view), and I think we can all agree on that. So the question becomes will BB6 put them back on the map for the consumer market? They have always done very well with businesses, and that market is going to be harder to crack. Although apparently the iPhone is the only approved phone for my Fortune 50 company which surprised me, but maybe their strength in business sectors is starting to be cracked as well. That's another topic though.
In the consumer space, people want apps. Period. With the iPhone and now Android, the app store/markets are what really draws people to smartphones. It's not the hardware or OS, as those have been around for many years, but it's the fact they have 3rd party apps that allow you to DO a lot more then just traditional phone, texting, pictures, and maybe some light browsing. This is where RIM has fallen short. Their marketplace sucks (as of my last experience with it ~6 months ago) and they have a very closed system on their phone, which is part of why they are liked for businesses.
RIM had a lot of innovative features that now are commonplace. BB Messenger was amazing and still to this day my favorite IM app ever, but my Droid's is a close enough replacement (although I still miss the part about knowing if they read the message or not). True push email is not done outside of RIM with the possible exception of Gmail/Droid, but my Droid gets the job done (through a more cumbersome polling method that means I don't get emails quite as fast). The physical keyboard of my Curve was amazing and crushes my Droid (which isn't saying much), but my Droid with Swype is close enough to my Curves keyboard even if I can't quite hit the same speed nor touch type anymore. Web browsing on my Curve was do-able, but not nearly as much of a positive experience as my Droid or iPod Touch.
There are many more things that I could continue with, but here is my point with all of this. RIM has a lot of features that used to be unique, but now are much more mainstream. They don't have anything that you can't get a close enough version of on other platforms. They haven't innovated with their devices IMHO, and the Storm 1 sucked. Storm 2 was better, but still suffered from flaws not to mention the negative PR from Storm 1 carrying over. The Bold was a good phone, but too late and is NOT able to compete with the iPhone (be it due to marketing, too complex compared to the easy to use iPhone, app market, whatever).
Unless RIM starts to bring truly unique features (hardware, software, or app related), and creates a phone people want like they want the iPhone/Android I forsee them becoming another Palm. Personally, I hope that doesn't happen because the Curve was the best phone I have ever had until my Droid. The jury is still out for me as to if the Droid or Curve is the better phone 6 months later, because of how great my BB was.
