then you might call it Choose Your Own Device) and even where it would it needn't be compulsory - I do not know anywhere where it is. As for the security side of things, well, that's something to manage but it isn't very difficult. If you use application virtualisation (Citrix or similar) you don't transfer any data to the device so you have as much control over that as you ever did (almost zero in most cases as anyone with any access to anything can export it and email it elsewhere - many business just wouldn't function is this was prevented.) I'd hate to be sat in IT going "No, you can't have that" to everyone - we have the tools to make this possible and so if people want it and are made aware of the risks where there are risks then why not have a go at getting it done? If one was serious about security email as it is currently implemented would be the very first thing to go - it's a nightmare of convenience and pragmatism - but I doubt it would go down very well with many organisations if anyone tried to prevent its use.
