Hey guys, I'm holding off on the purchase of the new 17'' i7 MBP until I get a better idea of the comfort when you're using it on your lap. I have a Pre-Unibody 15'' and the size is just perfect for browsing the web on the couch. I've been dead set on the new 17'' MBP, but I'm worried that the larger size, especially the significantly larger "palm rests" and distanced keyboard making it difficult or annoying to use on your lap. On one hand, I would love to have the highest resolution possible with the 17'', and the extra screen real estate is very nice. On the other hand, with the introduction of the higher resolution 15'' screens, it seems like I may be able to get the best of both worlds. So tell me forum, 17'' i7 or 15'' i7 with HD display for comfort on the lap?
