You and I have nearly identical use cases, interestingly enough.  My 
laptop that I'm using right now to type this is my development machine 
for a number of KVM things I do in the data center as well. Since I run 
it docked with ethernet on my desk, but not docked and on WiFi at home, 
I've had to do two things:
1.) A real shutdown when I leave work.  For some reason I've never be a 
fan of suspend/hibernate, and since I use LUKS I'd rather not leave the 
volume unlocked as it would be in a suspend/hibernate scenario;
2.) NAT-connected VMs in development, since I've never been able to get 
bridging to work properly over wireless (specification says it can't 
work, and I think that's true in practice, but I always reserve the 
right to be wrong!).

My laptop is at least as powerful as most of our servers, and it works 
great for development purposes.
