Am looking to switch to mac after using PCs for years, and need some advice. Waiting on the Macbook, really excited about it. 2 things: first, given all the speculation that the Macbook's internals will be similar to the Mac Mini, what is the likelihood that the CPU will be socketed rather than soldered (like the MBP)? second, any guesses about whether the MB will support screen spanning or clamshell mode? EDIT: Sorry for the newbie questions. obviously I know diddly about laptop manufacturing. thanks for the info.
