A:AnswerIT will hold anything up to around 9" tall x up to 12.5 " wide.
A larger item might fit , depending on the curves involved in the shape .
The thickness of the item should not matter , due to the way the divider between the compartments are constructed with flexability.
A:AnswerThis is the case for your laptop - you don't need to put the laptop in a sleeve or anything, there is a nice protection all the way around and unlike a sleeve, the case has structural support so it won't get crushed.
A:AnswerI recently bought my wife the 13.3 inch MacBook Pro. When I put the computer in the Thule case it seems as it has a little more room to fit a 14.2 MacBook pro. My answer would be Yes.
A:AnswerYes. At first I didn't think it would then realized the new MacBook is square edged and the case has rounded edges. Fits snug but I like it better than the Thule I had for the 16inch pro. Closes/zips nicely and fits cables/batter well.
