The first thing you need is a bag that's large enough to carry your kit but small enough to be easily carried and stowed when you're stationary. If you need to carry a laptop then my suggestion is the Timbuk2 D-Lux Messenger, a sturdy, well-made all-rounder that you can use when cycling, walking or struggling through an airport departure lounge. If you don't have to carry a laptop then you should be able to get away with a small bag, something like the Tumi Alpha.
For communication, photography, transit planning, note-taking and everyday mobile computing you could choose any modern smartphone by my recommendation is Apple's iPhone 5. It's fast, reliable, lightweight, easy-to-use and offers all the apps you're likely to need through a world-beating screen.
If you need a laptop then you'll want something small, light and fast. Apple's 11" MacBook Air should do everything you need (and you can install Parallels if you need access to Windows software) or you could go with a lightweight Sony Vaio (if you absolutely must have a Windows machine).
My advice would be to try to leave the laptop at home and do everything on a tablet instead. There are plenty of options in the tablet market but there's a reason that the iPad is the market leader and unless you have a particular requirement for something that the iPad can't do (which is possible, but unlikely) you shouldn't spend too much time on the decision; go to an Apple store, play with the tablets, leave with the one you fall in love with.
If you find yourself still needing to make written notes then a Moleskine Evernote notebook is the thing to go for. The smaller version fits nicely in the Tumi bag, the larger fits (just) but would be more comfortable in a larger bag. Pair this with a decent pen (like this one) and you're good to go.
To keep you going all day you will probably need a charger for your phone. Your best option is the Mu folding USB charger, which neatly circumvents the storage problems of UK plugs.
To round out your kit you will need a headset for hands free talking and musical entertainment. Something small and discreet with inline controls would be ideal and I would recommend the Sennheiser CX 890i In-Ear Headphones, which should give you complete control of both you phone and your tablet.
And that's it. You should now be fully equipped for a productive day's work away from the office. Just make sure you don't spill coffee or beer on your equipment.
