<p>DD1’s architecture laptop is a Lenovo T420 with the Nvidia graphics. As long as you’re not rendering the Burj Khalifa at 1080p 
it’s pretty good. You can’t believe the build quality of the thing - lightyears ahead of the usual Dells etc. Ok battery life. Lenovo gives some pretty decent educational discounts. Mrs. Turbo’s also lugging a T420 for work, the thing is on 12-16 hours a day, very good.</p>
<p>If graphics is not much of an issue (or as much of an issue) check out the Lenovo X230… Our industrial designers use the X220 for field work and it’s awesome. Built in Intel 4000 graphics tho, no NVIDIA.</p>
