Do you fly business or cattle class?
I guess it depends on how much you want to spend, what industry you work in and what level your at in your company. A senior level manager of a global investment bank is going to want something completely different to a charity worker flying Econony to check some water pump in the back of beyond*
Maybe one of these or these
I have items from both companies and have found them to both to be great in terms of design and ruggedness.
* in a way sad but true!
