Mini-metro for $96 is a great deal. I bought mine for $120 (regular price) mainly for the waterproofness and the ease of taking it on/off with the buckle.

I use it mainly for going to work/class and have a regular two-strap backpack for carrying more stuff when traveling/walking more. The straps make it easy to fit bigger or oddly shaped things into the bag too, when you need it.

I disagree with the cell holster comment above, but that's also because my phone is always in my pocket.

Definitely recommend the mini-metro. Enjoy your new bag!
