I work in education IT. I spent ten years going into RM schools, wiping their kit, putting it on plain Windows and Office that they were already licensed for, popping in once a week to keep it all running, charging less than RM did for a more rubbish service, and got nothing but more schools wanting the same after hearing about me.
CC3 was actually an improvement on the Connect 2 (as it was called) networks. CC4 wasn't much better either.
I could list stories for weeks on end. In the end, however, I got bored of taking all these schools under my wing and showing them sense and giving them less IT maintenance hassle (because they literally didn't need anywhere near as much support after I'd done this for them) and still receiving nothing but vitriol and lies from RM-sponsored Borough support outfits.
I went into the private education sector and pretty much every job since, when I mention RM and what I did for a living (and they phone up for references, obviously), they are just overjoyed to have someone who doesn't foist that junk upon them for the sake of "tradition" over just a plain AD setup with decent group policies.
Every job I've had in those years has been word-of-mouth from existing clients, in one form or another.
RM Easymail? Let's not even start. Anyone using it is an idiot to have tolerated it thus far, lack of SSL is probably the most minor issue I've ever seen with it.
About the only RM product that was any good was RM Maths for teaching kids maths, but technically it's still the same old RM shite in a wrapper, it just so happens they got a guy who understands how to teach maths to help write it (I'm a mathematician, so I can see that it's actually valuable as opposed to their talking-parrot-macro-stuffed-into-word that they actually SELL). I believe it's now a web service, as a lot of their software is heading that way.
