They make great hardware, and still have a vastly superior keyboard experience to any softkey phone anywhere. They have buckets of cash, and had great, really great earnings last year.
They have an ecosystem problem. This would be simple to remedy -- they just need to commit to HTML5 for apps, maybe adopt jquery mobile as a significantly-supported project.
Staff a small, awesome webkit team, and start making it dead simple to deploy to Blackberry. Start a webstore to compete with Chrome's webstore, but this one lets you take it with you on your Blackberry.
Second internal team would be dalvik support, adopting the android ecosystem. RIM never really made a ton of money on the 'app' ecosystem; this would put them on equal footing when being evaluated against Android.
I'll await my offer from the RIM strategy folks. : )
