Ask Engadget: What's the must-have gear for business travel?

Ask Engadget

Ok, last week reader Stephen D. wanted to know what the best Bluetooth headset was, this week reader Taylor R. wants to know, what's the must-have gear for business travel?

I'm starting a new job where I'll be on the road at least once a month, and I want to ask Engadget for some advice about are the best gadgets for business travelers. I've got my laptop and iPod, but I really could use some recommendations for a good portable mouse and a USB keydrive, as well as some suggestions about what other road warrior gear I need that I'm haven't thought of. I've also been wondering, are any of those WiFi detectors worth buying? Are they helpful?

Any tips for our new friend?
