Have the straps been redesigned? I like the idea of this case, but with several people claiming that the straps break ...I am concerned.

My straps have held up really well. The case comes with a long shoulder strap that’s not leather (not sure of what to call the material..it’s a woven material), and I use that the majority of the time.

Does this bag come in other colors?

Dear Lisa, our product department is planing to sell the bag in other colors,would you mind telling us which color you like?Thanks a lot for your interesting to the bag. :)

What is the internal dimension? Will it fit a 15" ultrabook which is 15" x 9.75"? Thank you.

Dear Valued Customer, sorry about that this bag can't fit a 15" ultrabook but this one ( http://www.amazon.com/dp/B00SXVPTUO) can.Hope it is of help. :)

will textbooks and a 14 laptop fit?

Depending on the size (thickness) of a textbook, you should be able to fit one or more in the briefcase. The pockets are generous enough to hold a decent-sized text (not a ginormous book). You should also be able to fit a 14-inch laptop in at the same time. This is beautifully made and very sturdy. I love mine!
