The Satellite case by PDA Concepts is a play-through case that will fit the following (but is not limited to) PDAs and mini notebook computers:
Newton MP2000/2100
Libretto 20,30,50,70
HP620, 660LX HPC
LG Phenom Ultra HPC
See PDA Concepts compatibility page for a more comprehensive list of machines that will fit in this case.

The Satellite case is available in three versions. Black or tan leather and black 1250 denier ballistic nylon with leather trim. Both come with a free shoulder strap. I'll discuss some other accessories that are available for this case later in the review. The overall size of the case is 10.75" by 6.25" by 4.75". The case has dual slider zippers that are smooth to operate and allow you to lock the case by putting a small lock through the 'eyes' of the zipper pulls. The outside of the case has two pockets. One has gussets with a fold over leather flap that is held closed with Velcro. This pocket can expand to hold a variety of items such as the Newton keyboard, Libretto external floppy, AC adapters, business sized envelopes etc. The other pocket is a flat zippered pocket on the back side of the case. This pocket could hold papers, a checkbook, etc.

Unzipping and opening the case reveals a very roomy interior. There are nine credit card / business card slots with one of them having a see through window. These slots are nice and wide so inserting and removing your cards is easy. Behind these card slots is a 5 inch wide pocket that can hold papers, money, etc. A stylus/pen holder is attached to the top of the pocket. There are also two mesh PC Card pockets that have an elastic stretch top. Inserting and removing PC Cards from these slots is a little difficult. The zippered wall of the case tends to get in the way. If you pull the entire card holder panel forward, it reveals another pocket that is wide enough for business envelopes, floppy disks, CDs, checkbook, etc. A divider accessory is available from PDA concepts that adds two more large mesh pockets. This divider attaches to the case with Velcro.  When it is installed, you wouldn't know that it wasn't

part of the original case. The main use of this divider though is as a screen protector. One side is made of soft Velcro compatible material that won't scratch a PDA screen (like the Newton) when it touches it. It also is great for use with the Newton holster. This leather accessory fits around the MP2000/2100 and allows it to stick (with Velcro) to the fuzzy side of the divider. When your MP2000 is attached this way, you can then put the Newton Keyboard on the other half of the case and type like you were using a laptop since the Newton will be at a good viewing angle. This holster also allows all ports to be easily accessible. Another special accessory is available that will allow you to attach your HP620/660LX HPC to the inside of the case.

The Satellite also works great with the Toshiba Libretto mini notebook computers. It is just the right size to hold the Libretto (with or without the port replicator attached), external floppy drive, and AC adapter. This makes a really compact way to carry all your gear with you.

Carrying the Satellite can be done one of two ways. You can use the shoulder strap that comes with it, or you can buy the smaller handle. I really like the small handle as it makes the case feel like a mini briefcase. But, either way, both methods are a comfortable way to transport the case. You can even put both handles on at once if you wish.

What makes the Satellite great is all the different accessories that are available for it.  Here is a list:
Small handle
Divider/Screen Protector - Adds two additional pockets and screen safe panel
Slip pocket - a small case
Battery pocket - small case to hold extra batteries. Has Velcro to attach to the inside of the Satellite
HPC elastic harness - For the HP620/660LX
Newton holster - For the MP2000/2100

The Satellite is a terrific case. The quality of the leather and workmanship are excellent. I could not find a thing wrong with it. It is now my favorite larger format gear bag. If you are looking for a professional quality case to hold your expensive PDA or mini notebook, you should really consider this case. And, you really have nothing to loose because PDA Concepts cases are satisfaction guaranteed.
