Stuff the battery life - fingers crossed for a decent screen size
From the photos, they look like 16:10 format. Anything less than 17"@1900X1200 is not good enough on it's own for pro use. The extra 20% vertical pixels make a world of difference. Plugging in a secondary monitor as a minimum requirement just defeats the purpose.
And might I say, it's about time too!
I wish Lenovo were still in this market. I'd love to update my 3yr old W700. Still, 3Ghz+8gb ram+raid 0 remains quite useful on the move, and nothing looks better to walk into a meeting with it, if only for the 'gosh thats a big one' double-entendre opportunities.
