Plain backpack to carry MacBook

I've used an http://www.llbean.com/webapp/wcs/stores/servlet/CategoryDisplay?storeId=1&catalogId=1&langId=-1&categoryId=38021&from=GM&noDept=&guideId=5953&moduleId=502215&feat=502215-dg essentially my entire life. It's pretty much as plain as it comes, really, the very definition of a generic backpack. And the value is insane; $24 for a solid backpack is not bad as it is, but it comes with a lifetime guarantee. I used to work there, and they hold up their end of the bargain--I had to re-monogram 15-year-old backpacks. They actually will fix it if it breaks, ever. Pretty sure my macbook fits in mine.

I use a http://www.patagonia.com/euro/en_GB_GB-/product/product_focus.jsp?OPTION=PRODUCT_FOCUS_DISPLAY_HANDLER&catcode=&style_color=48860 backpack. It's not tiny, but it's slimmer than many backpacks. It has a built-in padded laptop sleeve. It's very sleek and comfortable, I really like it. Patagonia also makes a smaller backpack called the http://www.zappos.com/n/p/dp/24036239.html that might fit the smallest MacBook.

I have been considering purchasing the http://www.ebags.com/sumdex/she_rules_153_nicole_modern_backpack/product_detail/index.cfm?modelid=67046. for my own MacBook. It has a very clean look and many of the reviewers say it fits their 13.3" MacBooks just right.

I love my http://goincase.com/products/detail/nylon-sling-pack-cl55026. It's only 5.5 inches deep and it's got a convenient pouch on the strap to hold an iPhone / iPod.

I noticed http://store.americanapparel.ca/rsanc501.html the other day. It comes in tons of colours.
