I mounted the front rack and added a basic Nashbar trunk to replace the aging (30+ years old) Himalayan handlebar bag that was wearing out. For commuting I carry my laptop and my lunch in a mailbag rear pannier, while I carry incidental cargo such as clothing and shoes in the front bag. I chose the standard trunk since it is big enough for this purpose, and a larger trunk would block my handlebar mounted headlamps. Other than than, there's no reason you couldn't mount a larger trunk, though I don't know if they come large enough to fit a laptop. Keep in mind handling issues with a lot of weight carried high up on the front wheel. You could also look at front panniers, but again, I think you'd want to balance the load pretty evenly on each side to avoid handling problems.
