I have a brand new HP Pavilion Laptop with a 17.3" screen display and finding a laptop bag/carry case big enough to accommodate my laptop WAS NOT an easy task! There were only 2 options that were capable of accommodating my 17.3" screen: a) a large "purse-style" bag about the size of an extra large beach bag and available only in loud and obnoxious colors, and b) a "student-style" backpack with a built-in pocket/sleeve in which to slide your laptop with a Velcro strap across the top of the sleeve to secure your laptop into the sleeve. While these options may be perfect for some people, neither option was right for me. I already carry a purse which is approximately "medium sized" every day, everywhere I go (and because my purse contains almost anything one might need when away from home, it has a fairly hefty weight to it), so the last thing I want to do is to carry around a second purse which is even bigger (a lot bigger) everyday. Especially one that is obnoxiously colored. Additionally, there is very little to no padding in this style of bag with which to protect your laptop. For these reasons, this option wasn't for me. The other option ("student-style" backpack) was somewhat better but still not really the right option for me. It was high quality and the backpack itself was water resistant. There were 2 main compartments in the backpack. The zippered compartment in the back half had a sewn-in padded sleeve in which to slide your laptop with a Velcro strap to secure across the top of your laptop to ensure that it wouldn't be moving around inside the backpack or fall out if the backpack if it were fall over while opened/unzipped. Then the zippered compartment in the front half of the backpack had all the components of a standard (large) student backpack including a smaller zippered pocket on the very front. While this backpack provided a little more padding than the "purse-style" bag, one of the drawbacks was that while the laptop sleeve securely held up to a 17.3" screen display, it was a tight fit. So much so that once my laptop was secured in the sleeve, the zipper was difficult to zip and the fit was so tight that the zipper scraped/scratched the top edges of my laptop. Plus, I really don't have any need or use for the front backpack portion. Both of these options are big enough to hold a 17.3" (and these 2 styles were the only options I found as it is extremely difficult to find bags big enough to hold the 17.3" screen laptop) but neither option really had what I need in a bag. After comparing these options with a sales associate, he knew that neither was really what I was looking for and he agreed that bags that hold the 17.3" screen were hard to find as he himself struggled to find one for his personal laptop of the same size. Then he said that there was 1 "messenger-style" bag that Best Buy usually carries that was big enough to hold my laptop but that it appeared as though they were out of them in the store and he offered to order one for me. I thanked him but said that I really needed something that day. He paused for a moment in thought and then said he had seen 1 or 2 of the bags in question stashed somewhere in the back where they didn't belong but that that had been the day before and he wasn't sure if they were even still there. After spending approximately 15 minutes or so looking in the back, he came back out to the sales floor where I was waiting and produced 1 "messenger-style" bag. He said that it was the last one that they had. It was professional and discreet in appearance, nicely padded for protection, had several interior and exterior pockets for accessories, a comfort padded shoulder strap and was made by a very well known brand name with a great reputation for making high quality luggage, briefcases and "messenger-style" bags. AND, it came with a 3 year warranty. It was EXACTLY what I was looking for!! I bought it right then and have used and loved it everyday since then. I have had other laptops and other bags but none of my previous bags were anywhere near the quality nor functionality of this Samsonite. If you have a 17.3" screen laptop, then this bag is a must-see. It has turned out to be everything I wanted and then some. I highly recommend it as being the very best option for this size of laptop.
