Microsoft has just expanded its own self-branded line of notebook bags with a unisex series. The Samsill-made bags were initially launched earlier this month with female-oriented models but now includes a much larger variety to accommodate more travelers. Cases start with the basic Zipper Laptop Binder ($45), a sleeve with a paper binder and pockets for accessories, and culminate in the Diplomat ($130) rolling case for frequent visitors to the airport.

Every bag holds at least a 15.4-inch notebook, according to Microsoft. The backpack models, including the pictured Summit ($80), also include a special pocket for MP3 players with a headphone port. All models are shipping today through a customized section of Amazon's online store.
