I suspect at least some of RIM's problems are due to their lack of support for ActiveSync. We look after 40+ companies' IT and always recommend Android or iPhone as proper BES support is ridiculously expensive and for most of our clients the security features within Active Sync are more than sufficient.
The abortion that is BIS email support just needs to be put out of its misery and they should support ActiveSync for smaller clients keeping BES support for enterprise customers where its features are appreciated (and affordable).
If Blackberry devices supported ActiveSync I'd have no problem recommending them to clients as the devices themselves suit some people, but at the moment supporting them is just a bloody nightmare, so the client receives worse service, so I won't recommend them.
