I keep getting dragged into meetings on BYOD and I can't escape thinking it's a fad to sell devices into corporate which are mostly not needed.
BYOD has gone from being a proposed method to reduce corporate asset ownership - which failed - to being about making people feel good because they get to use gadgets at work!
Here's an idea, get the best and brightest by offering a good salary, an interesting job, and looking after them well. Give them equipment which enables them to do their work and how about blocking any other devices so when they are outside work time they don't get work emails through to their personal device - simple step to help people walk away from work when they go home.
Personally before I have to spend money on new infrastructure, reduce corporate security, train and create new policies and procedures I like to see a far better ROI than 'it makes John in HR smile'.
