School Bags

This case is like a backpack of sorts its has many different compartments for your folders and papers. It has also gotten good reviews too.

I found that the Brenthaven messenger bag is excellent. It has great protection for your laptop and has room for other things suchs as folders, ipods, pens, and pencils. If you want a bag that is stylish, has great protection, lifetime warranty, and has room for other items.. the Brenthaven messenger style is the way to go. I can't remember the model number but they sell them in the Apple store.

you might like this MacCase messenger... seems very nice and has ample room: http://www.mac-case.com/MacCase%20Messenger.htm

my advice is to stick to backpacks because its less obvious that you have a laptop

http://www.ebags.com/ They have a good selection of many brands.

I would suggest that you get any messenger bag that you like from wherever, and then purchase an Incase Neoprene Sleeve for it. That will protect it from scratching and small bumps in and out of your man bag.

The reason I suggest doing it this way is because if you get a bag or suitcase made specifically to fit the MacBook Pro, it limits your style selection severely and will probably cost quite a bit more than a regular one.

I also suggest a back-pack as it is less obvious that you have a computer.

Here's what I did before looking for a bag:
- Decide what features you really want and what you can live without.
Examples 1) Pen/pencil holders 2) Outside mesh pocket for water bottle 3) Top entry for laptop vs. side entry 4) iPod pocket with earplug wire hole 5) Chest strap and or waist strap for use while bicycling

Then check out a site such as www.ebags.com where you can do side-by-side comparisons (this site has that feature so it's very easy to compare). You may find some things that you need to add to the 'must-have-list' and some that you will drop. Once you know that you should be able to narrow down your search.

Oh, and be careful to make sure that your MBP will fit as a lot of them are too small (again eBags has a pop-up box that tells you specifically if the MBP 15.4 will fit in a particular bag or not). Happy Hunting!
