I just ordered this from Carradice & to my surprise I got a $10 dollar refund as well. I also have a 17 inch Laptop & I find that there is little to choose from for Bicycle transport. This is about the best thing I have found. This bag is plenty big enough for a 17 inch lap top but the sleeve insert might be a different story. The bag is 17.3 inches wide & my 17" laptop is 15.5 inches wide. I'll let you know how it works out when it arrives.
