Which is the better display for macbook pro: matte or glossy?

MacBook Pro with Retina Display: is it usable outdoors?

• My primary reason for owning a laptop is using it outdoors.   Inside I have a 30" monitor with almost as many pixels as the Retina Display.   The rule of thumb for outdoors use is "matte, 400 nits".   While the new Retina Display appears to be quite bright, it does not have a matte option, although they are claiming "reduced glare".   I'm skeptical.   Has anybody tried their new MacBook Pro with Retina Display outside?

• Answer:

  You can use it almost anywhere. I have used mine on coffee houses, pubs, open offices, but when totally covered in sun light, like on the beach, nope, not really.  I have not seen any machine you can really do much work on at the beach or in direct sunlight, except for the e-ink kindle.  Though if pressed, you sure can, I have done so, once when a server broke, I was on the beach (on vacation), with my computer in my car. I sat at the next table with sunglasses, I managed to fix a code, test, publish and start the server, an hour or two of work with my iPhone as a hotspot. I could do it, I just would not do that again. A little sun umbrella would be a much needed accessory.
