A common note in these threads is that a lot of us have the same sort of gadgets (headsets, phones, headphones etc etc). Would everyone like to nominate their killer toy (oh - sorry - serious road warrior tool) of the past 12 months with a quick explanation as to why?
Favourite road-warrior gadget is a toss up between my Apple Powerbook G4 (great for watching DVDs in widescreen either on the plane or in the hotel room!) and the Sony Ericsson P900, which is about the only phone that I've found to have really useful features beyond dialling a number.
Not in the original question, but my favourite gadget that's tethered to the house (ie, not a 'road warrior' toy) is the TiVo. Sadly now difficult to buy a new one in the UK, but if you find one, snap it up. Changed the way I watch telly totally, and still way better than Sky+
