* Whilst I can't speak to the structural strength of the current MacBook Pros, I would be surprised if they were less than par for a typical laptop.
Having never owned a PC laptop you may be right there... I see quite a few broken windows laptops. Not much in the PC world matches Apple's industrial design. All I'd say is, never accidentally put too much pressure on an MBP's palm rest, over the CD slot. For that one slip, you have to replace two of the three major case parts costing a total of $400, probably $600 or more as a repair.
I can't help feeling that the way the MBP fits together mechanically could be a little less prone to issues. (e.g. Screens not folding properly, case seams not quite closing up, especially following a repair.)
