"Maybe a few servers?"
Maybe? What, so you expect PDAs to magically connect securely to half-a-dozen backend systems directly? And each of these systems have an interface in place to allow direct PDA access? What then, the PDAs download the full data from the system instead of going through an intermediate server which does smart stuff like caching data, only sending down the minimum, compressed, encrypted data to the PDA?
I'm sure the police don't need to pay anything for network access either. Yes, Vodafone or whoever are just going to dish out gigs of GPRS access for free. Oh and of course data access is a one time cost anyway, isn't it? The police aren't likely to be using the devices for several years or anything.
I also imagine that other costs like mobile printers, adapting police uniform/holsters to carry PDAs and printers, servers, software licensing, officer training, spare devices for losses or training and storage/charging lockers for the devices don't need to come from this £50m budget?
I have no doubt that some companies are doing fairly well from this, but please actually think about what you're saying before coming up with a hilarious bit of maths.
As for it being 10x faster for officers to radio in, where are you getting that from? You do know that half the goal of using mobile devices is to *cut* radio traffic which is already bad enough? I don't think flinging hundreds more officers at the system either would help that. I doubt that officers want to wait even longer than they often have to in a queue just to get to a radio operator.
Not forgetting that the operators can only access a couple of systems like PNC, while the PDAs can be used to access multiple systems at once (PNC, intel, crime, electoral roll, tickets, warrants, firearms, etc...) from a single search.
Ok, fair enough. Let's stop this police madness here. Throw away all the thousands of devices that are currently in use (since around 2003 on) across mobile data trials and full-blown roll-outs around the country. It's clearly of no use to anyone.
My sarcasm levels are running low now, so I'll just say that some of your points are valid indeed, but I just had to vent on the some of the stupid stupid stupid things being said. Come on, this isn't the Daily Mail messageboards, you know.
