I'd like to share another experience with the Zagg InvisibleShield on the Nokia N900. Personally speaking, I have been reading a lot of other reviews, opinions and comments online and couldn't really summarize it or to make up my mind about the product in question. So finally I decided just to try it myself and placed the order.

Upon receiving the package a week later, I found that the application solution box with the sponge had leaked and there wasn't much of it left to be used. No worries - I prepared a solution with dishwashing liquid instead, which was suggested by many. It worked really great, so no problem with that part.

I prepared quite thoroughly as I didn't want absolutely any particles of dust to get stuck underneath the shield. I did the whole process in our shower room after sauna, so the air in the room had been hot & humid for hours, eliminating any dust that could be floating around in the air.

I cleaned the screen with window-washing spray and removed all the dust particles from it after it had dried by gently brushing it with a paper napkin. It even stayed clean for the following minutes, as the air was dust-free.

Then I cut out the screen protector from its plastic bag in a way that a part of the plastic was still attached to the front side of the shield, so that I could handle the film without having to touch it. After removing the paper backing, I sprayed the under side with the dishwashing liquid solution. Same spray went on the N900's screen.

The application went smooth - much like you can see on many videos on Youtube. End result was awesome: no dust or bubbles whatsoever. There were some microbubbles, but they dissolved overnight just as the manual said.

For the visual appearence, I was really satisfied. I had not been expecting much, but the device looked as good as it used to and didn't catch fingerprints as it had been doing before. From all the things said online, you can really believe that the Zagg leaves the N900 looking almost OEM.

However, the same cannot be said about responsiveness and the "feel" of the screen. Even as the shield is 0.2mm thick, it certainly adds another layer between the touch-sensitive screen and your fingers, so you lose a bit of the original insane accuracy.

Secondly, the Zagg shield does "improve grip" as promised or in other words: it makes your fingers stick to the screen. While this effect reduced after settling in overnight, it certanly does *not* provide the same smooth and slippery surface as the naked N900 does. I suddenly found myself in an annoying situation: when I swiped the screen gently, it didn't register anymore (or worse: it registered intermittedly) and when I used enough force, it scrolled/panned perfectly, but my finger started getting stuck all the time, so the movements weren't smooth anymore.

This got really annoying. I wasn't able to carelessly browse around in the media player or the web browser as I had gotten used to without the Zagg shield. Instead there were many mis-clicks and skips occurring which sometimes made using the interface quite hard.. and definetly not as joyfully pleasant as the N900 I had started to like so much. I started to realize that when you put anything at all on a delicately calibrated touchscreen, it's bound to change..

Personally, I simply love how the Nokia engineers have designed the screen and I wouldn't change one bit in it. I've seen many remarks online which are saying that the N900 is at the very peak of what is possible with a resistive touchscreen and I couldn't agree more. I find that the accuracy, ease of use and the possibility of using your gloves or a stylus absolutely put any capacitative-screened iPhone to shame. Anyone that has used a N900 can testify to that..

So in conclusion: even when the Zagg shield looks great on the N900, you won't experience the engineering wonder of that touchscreen anymore: scrolling becomes jerky and it's less accurate when doing anything but simply tapping. Maybe it just needs time for getting used to.. but frankly this was still too high of a price to pay. I removed the Zagg InvisibleShield from my N900 about 24h after applying it - it's just not for me.

I really hope that my experience will help someone else make up their mind and try another manufacturer's shield instead.. or just buy a leather case for the device like I did last week and leave the screen as it was designed.

Cheers!
