Ah, that may explain the little groups of people (about 10 or so) that I have seen from my office window in Southbank the last couple of days...
No uniform yet, just regular clothing.
They have been standing around tapping away on what look like HP's 6000 series - with the stubby mobile antenna sicking out - don't think Dell have a phone version PDA (at least not here yet). Bit hard to tell exactly from a few floors in the air...
Some of them have got what appear to be small printers hanging at the waist, maybe WiFi or bluetooth connected.
If I spy them again I might duck down and have a 'sticky'
and get some more details.
