Just wanted to throw my 2 cents into the mix.
Originally, when iPad had released, I had ordered an Ultimate Sleevecase.
(My review here:

It has been precisely what I was looking for in regards to protection, and I am as happy with it today as I was when it arrived
I have been so happy with the quality, I had wanted, but struggled since I got my Sleevecase, with pulling the trigger for a Muzetto only due to price. After having gone through 2 portfolio bags in a year, I started thinking harder about value for the dollar. The Portfolio bags were not the greatest in portability, and the durability wasn't always the greatest with ripped interior pockets, and faded leather. I could fit a lot more in them, but trips to the city weighed heavily on my shoulder, and the size would take up a whole seat next to me, or leave no legroom by my feet.
So I finally decided to pull the trigger and weather out the wait times to get my Muzetto. I had initially ordered the Muzetto Portable with the black trim. Immediately after exiting my order confirmation, I had concern that it may be too small. Watching more reviews of it on youtube, I emailed a couple of the reviewers and came to the conclusion that I would be happier with the 13" Laptop Muzetto, I contacted Waterfield who responded promptly that the change was no problem.
I finally received it last month, it was delivered in a US Postal Priority box. Opening the box revealed my Muzetto sitting in a large clear plastic bag with simple packaging. It did not come with the removable straps which I was actually happy about, and it came as a nice rich brown color completely comparable to the color shown on their website. The color reminds me of a nice bomber jacket, The leather has a "broken in" flexibility to it, it has such a quality feel, I would love to have a leather jacket with leather like this. I know I am repeating many other peoples sentiment, but the stitching was done so well, I have no fear of it loosening. The only thing that surprised me a little bit was at the top of the bag just above the stitching on the sides, there was a little loose oilly substance, I don't know if it was a little glue or leather oil, it was no big deal, I just wiped it off.
The inside material is of excellent quality as well. It is strong, I have no fear to the lining or pockets tearing on ripping. You've all seen the photos of course of the orange toned liner, and the soft neoprene pockets, this is a bag that will last a good long time.
As comparison for those that own the Ultimate Sleevecase with the leather bottom, this is the same leather. The black coloring appears to be the same material used.
It is definitely lighter weight than the portfolio bags I have lugged around for years. The vertical shape definitely adds to it's more portable feeling. The strap is simple, I like the touch of the textured no slip shoulder pad that is installed using velcro so as the bag slides from your side to your back, the shoulder pad stays in place on your shoulder. There is a little annoyance of the sound of the strap moving back and forth with the hard plastic D-Shaped holder, but again, thats just nitpicking.
I am definitely glad I moved up to the 13" Laptop bag. I think for me being a large guy, the portable would had come across as a murse, and larger would had been too large, this is the perfect size for me. Interestingly though, my girlfriend did call it a "man bag" and told me she would had suggested differently had I shown her I was going to purchase this. This is because it only comes with a shoulder strap and no handle. This is also a woman that believes T-shirts with pockets are for old men, as well as me drinking Coffee in the middle of the day is an old man thing

she and I have very different taste, so I don't necessarily put much on her saying that lol This is a very masculine bag. IMHO this works well at the office wearing business casual, as well as T-Shirt and Jeans on the weekends.
Primarily I use it for my iPad and cables, some work related paperwork, my morning breakfast bar and lunch, my portable camera and some odds and ends things I need to carry with me when mobile.
It is an excellent bag. I am glad I spent the money, it is well worth it.
