Use: I will be using this as a home to work bag. I walk some, take the bus and the metro.Required features: Spinner, room for laptop, books, lunch, iPad, knitting and if necessary enough clothes for a weekend. Comfortable handle or backpack/messenger options.Pros: It rolls wonderfully and fits through different size aisles. I'm not sure about a 17" PC by my 14 x 9.5 work laptop fits fine. The zippers are sturdy and there are enough compartments for all my needs and more. If a laptop doesn't fit in the designed sleeve, there is plenty of room in the main compartment for the laptop and more. The bag is not heavy and has a nice multiple height handle. One person thought the handle felt like it would break easily, but I have had others that were shakier that lasted years. The warranty is definitely a plus along with the sale price!Cons: It is taller than I like and friends who travel more than I do said it would probably not fit under a seat but would be fine in the overhead compartment. I would have liked larger wheels to help in rolling over more surfaces such as some carpets and unpaved walk ways.I looked at all the other PC bags with the spinner feature and they are based on the traditional computer/folder/office design. This was more than I needed. This was the only spinner backpack I could find. I just want to carry my computer without pulling my shoulder out of joint. I want to be able to reach in without having to open the compartment completely too.I like not having to open the whole thing to get to my laptop and feel it is well protected from bumps and gouges.
