Cases?

I am looking for a case for my new 12" PowerBook, and I am debating between a Marware Sportfolio Sleeve, a MacCase sleeve, or a RadTech sleeve. I will be carrying it in a backpack most of the time, but also by itself once in a while. Any suggestions or experiences or recommendations?

I bought the incase sleeve from the Apple store a few days after I got my 12" iBook. It is nicely padded and perfectly sized for the 12". It has a removable shoulder strap and two handles which can be inverted into the pockets on each side (good for using just as a sleeve). The zippers only open about an inch down the sides which I think makes it easier to slide the computer in and out. The pockets don't have a lot of room for accessories. It does fit the power supply but tends to get a bit bulky. Overall, it has worked great for me and I highly recommend it.

Well, I ended up investing in a SpyMac.Case. It was cheaper to buy a whole bag than it was to buy a sleeve, and the bag had some storage room for bare minimum of stuff. I decided that it would suit me better so I could carry the power adapter, mouse, a notebook and folder for classes, and CDs or other small assorted stuff. Hopefully it will work out well.
