We have a Ponte Vecchio Lusso and a Mazzer Super Jolly. A pretty basic set-up, but it serves us well.

We got a Nespresso machine in the office (common thing in hitech firms here in Israel) which I must say makes decent coffee with minimum fuss.
We also got a super-automatic which makes undrinkable black liquid.

There are many places in walking distance making very drinkable cappuccino with latte-art (I ask for replacement when latte-art is in poor form as it usually indicates careless Barista)

When I'm in the US office I switch to tea

My office setup is a PeDe hand grinder and several Bodum Brazil French presses. I found a good deal on the French presses on ebay, so I bought enough so that I always have a clean one on hand. The dirty ones go into the office dishwasher.

I used to make press coffee using the office's coffee (Allegro cafe blend), but after I started home roasting two years ago I realized that the Allegro at work was very stale. Now when I brew up some freshly roasted SM Yerga Cheffe I get compliments from my coworkers on how great it smells.

I was about to start a thread like this until the google search "office site:home-barista.com" lead me here (after I passed by the results about the Expobar Office). Like George in the OP, I'm using an Aeropress, hand grinder, and a small electric kettle. They fit in the bottom drawer of my cube and take about 5 minutes from opening the drawer through closing it when I'm done, including the unbeatable Aeropress cleanup. Drinking the cup takes about as long as an espresso shot as I'm not making very big volumes; I have yet to experiment extensively with any inversion techniques (and due to the clean up issues involved, I'm leaving out anything but the disposable paper filters).
