So much HP bashing in here so I'm going buck the trend.  After a few personal recommendations from a couple of my (non-concerned) vendors I've continued to buy HP (pro/elites) for our staff and they've been fantastic.  We've got a couple of ancient models that have just kept trucking on.  Plus replacement parts are comprehensively readily available online.  Staff have been impressed with their HP's and I've had requests to be able to buy them at end of life.

I've dealt with their 0800 support line and they've been straight to the point with no scripting to get past (Toshiba was awful, had an issue where they would not boot/restart when docked and ended up returning a bunch of laptops because of it).

Their range seems to be the largest, especially when looking for a real docking solution (ie, not a USB port replicator that doesn't charge -- yes I'm aware charging via USB models do exist) and a full keyboard with a numeric keypad.  When filtering down what's available with a customer's requirements for a laptop there's always an HP model that fits the bill.
