first order of business, a case. i've checked out the speck cases in person and while they look like they'd do a good job keeping scratches away they felt a bit flimsy. is there anything like the speck case that's a bit more rigid or is that about it for hard covers? any macshack crew have a laptop backpack with a compartment for camera gear? needs to hold 15" mbp in a padded laptop pocket that can also hold the laptop in an additional sleeve, regular backpack compartment that can hold a binder and at least one text and a section on the bottom that can hold 1 DSLR with a good sized lens attached an an additional lens. other pockets would be nice as well for things like calculator, flash, etc... is the mushkin ram from newegg any good? any of you have a carapace silicon keyboard cover? any good or better options?
