I received my Muzetto bag on Monday and it's really great. I wanted something that could carry the iPad, wireless keyboard, camera connectors, stylus, headphone, etc. and an actual notepad (yes, I do still use paper and pen). It's very roomy without the wireless keyboard and a tight squeeze with it. Not painfully tight but very, very snug. I suspect some of that will ease as the leather lossens up a bit with use.

I got the 10" bag with the Flame accent. The leather is very supple, the fabric finishing really nice and the overall workmanship is really excellent. I'm a long time sewer so I've made a few bags in my time, although not with leather, and they do a great job. It's definitely pricey, but worth it for the quality and even the looks. I don't carry a purse or a briefcase anymore, haven't for years so if I'm going to carry a bag I want it to not only be "pretty" but exceptionally useful. I still have to carry something occasionally for my paperwork, but that's not very frequent so this bag works for what I carry now.
I'm using the Apple Case for the iPad vs. something bulkier. I haven't been carrying the charger with it in the bag since I've got one at home and one at the office. If you want to carry all the accessories with it, or the keyboard dock you might want to look at the next size up for the extra room.
