Hi. I've been planning on getting a 15" AlBook, but between the interminable shipping delays and the dodgy quality -- some people still reporting display problems *after* the fix -- I'm thinking about upgrading to the 17" instead. I'm not planning on going mobile very much at all -- perhaps to a friends house or a coffee shop every now and then -- but the entire reason that I want a laptop rather than a desktop is so that I can be untethered around the house. I want to be able to sit crosslegged on the couch and use the laptop, er, in my lap. I'm concerned that the 17", while it would be great on a desk, might just be too durn big to use as a lounging-around laptop. What do those who have it think?
