Since the new REX Pro model was released, a few new cases for one of the worlds smallest PDAs have also been released.  Here is a short review of cases by Tech Center Labs and the Mini-flip cases by K&K.

Crystal Hard Case by Tech Center Labs

The Crystal hard case by Tech Center Labs is really a PCMCIA holder that has been modified so that you can use it as a play through case for the REX.  When the case is closed, the buttons on the REX can easily be activated via a cut out area.  This is a terrific case because the only time you need to remove the REX is when you want to sync it to your PC. 

Inserting and extracting the REX from the case is simple. You just open the cover and pull out the PDA.

The real beauty of this case is that it is made of hard plastic... hard enough so that you can even put the REX in your back pants pocket and sit on it without fear. The plastic case keeps the REX from any flexing that might cause the screen to break. 

One nifty idea that you can do with this case is cut out a photo and put it upside down under your REX. Since the case is play through, you can see your picture when you turn the case over.

This is the only case I'm using for my REX! 

Price: $12.00 ($4.00 for an unmodified case - non play through)

Pros:
Protects the REX from flexing.
Play through - buttons are exposed when case is closed.
Made of see through clear plastic.

Cons:
None.

WetSuit Case by Tech Center Labs

The WetSuit case by Tech Center Labs is a flexible rubberlike sleeve. You can slide the REX in and out easily. It will protect the PDA from scratches, dirt and splashes.

This slip case would be useful for someone that carries their REX in a purse or jacket pocket. It will keep your PDA from getting banged around against other objects.

This case won't protect your REX from flexing. It is strictly a light weight slip cover.

Price: $8.00

Pros:
Lightweight.
Protects screen from scratches.

Cons:
Not play through.

REX on a Rope Case by Tech Center Labs

The REX on a Rope case by Tech Center Labs is a see through polypro case with a metal ring attached. It comes with a string attached that would let you wear the REX around your neck. You could also attach this case to a key ring.

To insert the REX, you just snap open the lid at one end and slide the REX in or out.

Since the case is clear, you'll be able to see an alarm when it goes off on the screen. The case is also large enough to put one credit card or a couple business cards in it.   The case is also pretty sturdy and as far as I can tell, would keep the REX from flexing. So, it's possible that you could put this case in your back jeans pocket without fear.

Price: $12.00

Pros:
Lightweight.
Protects screen from scratches.
Seethru.

Cons:
Not play through.

FieldPak Case by Tech Center Labs

The FieldPak case by Tech Center Labs is a heavy duty high protection see through case.

The cover opens like a clamshell and is held closed by a snap closure. It's a strong snap so I wouldn't be afraid of it popping open on its own. Inside the case is a shock absorbing gel like pad that the REX sits on. When the REX is resting on this pad, there is room under it for extra batteries, small folded notes etc.

Standoffs on the lid of the case press the hold the REX securely in the gel cushion. This case is padded enough that I wouldn't be afraid to toss it across the room or put it in my back pocket. The only real bad thing about the FieldPak case is that it is pretty large compared to the REX itself. Its overall dimensions are: 4.25" x 3" x .75".

Price: $12.00

Pros:
Shock absorbing.
See through.

Cons:
Large size
Not play through.

Mini-Flip Cases by K&K

K&K makes two different cases for REX PDAs. They are called the Mini-Flip cases and are black heavy gauge vinyl play through cases. 

The REX slides into a clear pocket on one side of the case. The other side of the case also has a pocket (non-see through) that you can put business cards in.   

While the REX is in this case, the buttons can easily be pressed through the plastic. The plastic protects the screen from smudges and scratches.

The other version of this case is called the Mini-Flip Plus.  The only difference is the addition of a thin flat magnet (1/32" inch thick) on the back of the case. You can use this magnet to hold the REX and case on to a refrigerator, metal cabinet or any other metal surface.

Both Mini-Flip cases are small and light weight. I like these cases better than the original case that comes with the REX because they don't use those four little elastic bands that tend to obstruct the buttons.

This case isn't strong enough to allow you to put the REX in your back pants pocket though...

Price: Mini-Flip $4.00 ea.  (price is lower when buying in bulk), Mini-Flip Plus $5.50 (price is lower when buying in bulk)

Pros:
Play through.
Inexpensive.

Cons:
Not strong enough to allow you to put it in your back  pants pocket.
