For stuff like this, it only takes a job to require it, and then it gets into the persons life.
I had never used skype as I hate phones, but my last job, the bosses use it, and so I got it as an IM app. Probably wont uninstall it and might keep it on future installs as it might be handy.
Cloud things...Kinda already have that at uni, but its more of a small drive partition on the network. I can expect it though to roll out quite quickly once it becomes mainstream, as at the moment at Bmouth Uni certain computer labs have certain bits of software, being able to use any computer anywhere for your stuff will be very good, when the teaching lab is booked out and you have an assignment to do which needs one of the computers.
Id imagine the students would get used to the cloud system and then not really have an issue with it in the future.
I think my mum has access to vm system on the NHS but doesnt really use it due to the slowness.
About the only person I know who is paranoid enough to not want to use something like this is my sister. But I think shed be open to the idea if her work forced it on her.
Will be nice if these fibre city things go ahead
