Re: They should try to hold on
I think I agree.
Why do companies only have to have one product (set) ?
Apple appear to have/had several products: iTunes-iPod/iPhone/iPad, Laptop-accessories and iMac-accessories; not all were madly successful, so were quietly dropped. Nokia although providing several services which made their phones better, but seemed too willing to let an incompetent carrier replace them, I think it would be better if the carriers just bought a complete package, instead of not understanding the tech they were selling.
People will put up with an unreliable product and even say it gives it character, but when they are able and can afford a more reliable one they will switch (perhaps after a morning period). Reliability is one aspect of usability, important when you depend on it for communication with family and friends or colleagues and clients.
I think Blackberry should have been in all aspects of company - mobile device communication, a speedy, secure and reliable link between, say, architect's office and their pad/book for showing a client plans. Managing lost mobile devices, not just remote wiping private data, but providing alternate access to that private data - leave your phone on a train, just go to a phone shop at the station, get a replacement (for a cost), type in a configuration key and carry on.
