I you want to buy the X1 Extreme or P1 just buy an XPS instead. Lenovo outsource sales and logistics to Digital River who are hands down the worst organisation I've ever tried to deal with. They don't respond to emails, ignore direct questions and leave tickets open for several days at a time without status updates while they wait for other departments to respond to them. My new £3.5k laptop shipped with clearly visible defects on the screen and requesting an exchange be shipped prior to collection of the system (so I'm able to work in the -- shipment of the new machine will happen within 15 days of receipt!) required escalation. Lenovo and Digital River have no process for supporting their higher end models. Avoid at all costs.
