A few hours of usage behind my first laptop purchase (ever) I'm pleased with many things, but... 1) The screen. By far my biggest gripe. The vertical viewing angle on my (LG) unit is lacking. It performs well on white backgrounds, but less so on darker color schemes (as I use with Vim). With a darker setting a clear gradient is visible on the top 1/3 of the screen affecting readability when the viewing angle is not spot on. 2) The trackpad. Not sure if this is due Lion, or my lack of familiarity with some conflicting gestures, but at times simple clicks are unresponsive. I've checked one-tap clicks from settings and sometimes they just don't register at all. On iMac's (Snow Leopard) equipped with a magic trackpad I've never noticed anything similar. 3) Instant On? As many have already noted, it's not that instant. A few seconds goes by before I can type in my password to login. What does everyone else here think of the screen? Is it usable as a main machine, or needs to be hooked up to a big screen?
