Why do you take your laptop home with you? Why not just leave it plugged in at work (or get a workstation with more power for less money)? Surely you can ssh (or vpn) in if you need to work from home?
We have a crazy corporate security plan, everything's encrypted, limited out-to-in network access etc. Most of the major systems are only accessible from your internally assigned IP, etc. VPN only auths from our issued computers, servers only auth from those computers etc.
It's all pretty seamless from our issued computers, but it's a pain inducing minefield trying to do anything outside of that.
It's just a rMBP, so it's not like I'm huffing around a 12lb Dell monster or anything. But it seems kind of pointless when the computer in my pocket is good enough technologically for most things.
