One of the first things I did after buying my TR was to snag an appropriate case for it. My first purchase was the Targus DVD001 case. It worked, but it was really meant for a DVD player. Most of the storage space was for DVDs, not for things like the power supply, which didn’t fit in the main compartment along with the TR. The case ended up being a little too bulky for me. After all, the TR is an ultraportable.
A few suggestions from some Mac-head friends of mine led me to Waterfield and after checking out an iBook case firsthand, I liked what I saw. After emailing them, they told me that a TR case would be available a week after my inquiry. I’ve had my case for a little over a month now, and so far, it’s been a good experience.
This is a very well-made little case. It’s a ballistic nylon sleeve lined with neoprene. It’s specifically made for the TR, so it fits it like a glove. There is literally no lateral space on the sides, so I can’t fit my fingers in at the sides of the laptop (mostly due to the neoprene bunching there), but there is enough give at the top and bottom of the laptop to slide my fingers in easily to grasp the machine to pull it out. Even thoughs with large hands should have no problems getting them in. There is a nylon loop at the bottom of the case to hold while you pull the laptop out with the other hand. The neoprene lining doesn’t give the laptop the same protection you’d get from a full case, but it’s enough that I feel comfortable using this alone case as my daily carry case.
The basic SleeveCase is designed as a protective sleeve for your laptop to put in a larger bag. To that end, it will make your TR about 2 1/4” thick. The model in the pictures has three options added to it to make it into a useable stand-alone carry case. First is a large flap to keep dirt and water out of the laptop compartment. The flap is wider than the top of the bag, so it’s adequate for keeping out light rain, but I’d worry about it during a downpour. It’s been kind of dry here lately, so I haven’t had the opportunity to test this much. The non-flap model has a small nylon strap with velcro on the end to keep the laptop in place, if you were curious. The second option I have is a pretty nice shoulder strap. It’s got adjustable straps, a pair of heavy-duty metal clasps and a sizable 9"x3” neoprene shoulderpad. The last option was the piggyback bag to put things like the power supply in. The top two corners clasp directly to the same D rings that the shoulder strap does and the other two hang free. Inside the main pouch is a smaller, net pouch for holding small objects. Sadly, this was the one thing I wasn’t quite happy with on the bag. Due mostly the size of the TR, the bag is incredibly small. I typically carry the TR power supply and power cable, glasses cleaner, a short network cable, train schedules and my BT dongle in it. That’s about all it fits. I might be able to jam in a CD jewel case, but no more, so if I want to bring along a mouse, it’s not going to work. The net pouch is a little too big to be a place to put small objects in. I found that I had to go fishing for my BT dongle pretty often and would have liked a small wallet-sized pocket with a secure flap for storing it in. As you may notice from the picture I ended up using a keyring to keep the BT dongle case in place. Thank you Sony! 
I definitely understand the difficulty in adding a storage pouch to what is essentially a laptop sleeve, and it’s a reasonably elegant solution, so I won’t hold this too much against the case. It will definitely work if you want to carry around just the power supply and a few cables and dongles.
The workmanship of the case itself is top-notch. It’s very well machined and uses high-quality parts. It’s a good thing too, because this case is pretty pricy. The base sleeve itself, fit for putting in a backpack is $37US, but once you start to adding extras, the cost starts to skyrocket. The fully tricked-out model I bought came out to almost $100US including shipping. It’s definitely not the cheapest carry case option, but it’s well worth the money if you want a slim, well-made carry case specifically made for your laptop. I never get tired of hearing “There’s a laptop in there??” :D

Following are some pictures of my case with the shoulder strap, ballistic flap and piggyback bag options purchased:
The Waterfield SleeveCase - A close-up view of the case itself, especially the dirt flap and the big shoulder strap clamps at the bottom.
The TR sitting directly on top of the case
The TR inside the case - The TR fits perfectly width-wise into the case. The top lip of the case is taller than the TR by about 1/2”.
Close-up of the lip of the case - An extreme close-up showing the thickness of the neoprene. There is a good amount of padding protecting against a side impact.
The Piggyback - It’s actually smaller than it looks. It’s wide enough, but I think it could have benefitted from being quite a bit deeper. Right now, it’s almost filled to maximum.
Inside the piggyback - Here you can clearly see the inner net pocket. The netting is made of nylon and is about as tough as the rest of the case. Thankfully Sony thoughtfullness and a spare keyring solved my BT dongle hunts.
