Good signals for T-Mobile and BT Openzone in main concourse (by the big central Starbucks). Not an abundance of power sockets but a few around (I was there early but not so early as to crash with Hoover-wielding cleaners). There was though a T-Mobile 'HotSpot' - an area of seats where powerpoints are provided., There are also a few fixed line connections, now fairly standard at BAA airports. But at £1 or €2 for 10mins, that's steep unless there's a vital email or travel doc waiting for you on some webmail account., At my gate (29) there was also a T-Mobile facility to stand, plug in and work, and The Cloud joined the list of wi-fi providers with its own decent signal.
