I built a cardboard mock-up of my on-order 8790 and went backpack shopping with it today. It just barely fit in the Targus Sport Standard pack.
According to Targus's product overview
, the only difference between the Sport Standard and the Sport Deluxe is that the Deluxe "includes a flap that comes over the front of the backpack and clips shut."
However, if you check the Product Details, the Sport Standard (the one I treid) reads
11.5" x 2" x 15"
(Note: Will fit most notebooks with a 15" screen)Exterior Dimensions
17.75" x 7.25" x 21.63"
While the Sport Deluxe readsDevice Compatibility
13.6" x 2.2" x 12.9"
(Note: The computer compartment will hold most notebooks with a 16 inch screen and also compatible with Apple® PowerBooksTM with 17" screens)Exterior Dimensions
17.75"x 8"x 21.63"
So it would appear
that the Sport Deluxe is bigger and, since I could fit the 8790 model in the Standard, the Deluxe should work best.
I know, however, that Usrbingeek is using the Deluxe; he says in his review that the 8790 "just barely fits in." The Deluxe specs 2 inches more laptop width (13.6 vs 11.5) than the Standard. So if an 8790 just barely fits in the Sport, it should be roomy in the Deluxe. Which means that Usrbingeeks wouldn't describe it as "barely" fitting.
Also note that their exterior dimensions are almost identical, and my mock-up was barely shorter than Standard pack.
I conclude that the Deluxe does NOT have more room than the Standard. Targus is just relaying different measurments for the notebook capacity.
