So, I'm looking for a bag, and have finally settled on something from Crumpler after hearing nothing but glowing reviews (I also found out they have a store downtown!). Right now, I don't think I'll be moving my 15" MBP out and about just yet, so I'm thinking about getting a green/yellow School Hymn or a Considerable Embarrassment for use with school even when I'm not carrying my MBP around (I need a new bag anyway, but after seeing it in person, it's kinda huge...but I guess that has to do with the size of what it's intended to hold). I also hear that Crumpler's warranty is covered as long as the original buyer is still the owner of the bag.. true? So enough of me, what do YOU have? Why?
