Most users of mobile devices such as Pocket PC, Palm and Symbian Smartphones don't give any thought to protecting one of the most important parts of the device: the touch screen.
This is a mini-review, since the product we're looking at doesn't have specs or software to try. It's pure hardware. The Martin Fields Overlay Plus uses a gentle adhesive to stay in place on to your PDA screen. I have used this product on my Sony Ericsson P800 for some time now, and it's perfect for protection against dust, liquid spills, fingerprints and of course scratches.
Doml has sent me a sample of their Martin Fields Overlay Plus for my current Pocket PC, a HP iPAQ h4150. Installation is simple, but I'd recommend peeling off only a little of the backing, aligning the edge carefully and then peeling off the rest while using a credit card to make sure no bubbles are left behind. It should take less than five minutes to clean the screen and apply the protector.

Here is a real life example of how important it is to protect your handheld agains scratches. Look at the picture below. The photo below is of a HP iPAQ h3970 with some scratches created by... playing Solitaire! On the second image you can see how the scratches correspond to the location where the deck of cards is, and where the first card is drawn:
How can this be possible?
Touching the cards
The protectors are washable and reusable, and you can't see the plastic after it's applied. It helps reduce glare too.
To test the screen after applying the protector, I tried three different styluses. I have an old (but hard to beat) Cross DigitalWriter (I'm pretty sure they don't sell these anymore), a Cross MicroPen (which is a perfect fit for some Palm devices) and the HP iPAQ h4150 original stylus. The feel on the screen is good, without any scratch sensation when writing. It feels like a brand new screen actually. The stylus glides over the surface, and recognition remains accurate.

Current prices are around US$24.99 (twin pack) for almost all handheld devices. For this price, and after seeing what can happen to a screen with repetitive use, I think this is well worth the low cost to protect your substantial investment .
PS: the damage to this screen occurred after my girlfriend inherited my handheld.
