Not cheap, but...
It's an upgrade over the outgoing version without an additional gouging for more money. So for the same price you get 64Gb of ram and and 'better' graphics card. The previous keyboard was awful for touch typing as there was no feel to it. They've also sorted out the cursor keys - back to the inverted T format.
However, buying an additional power brick will need you to fork out for another cable on top of that. And a load of dongles.
How about the £200 leather case for it!
