I love my Centro. Of the 10 or so, it is by far the best phone I've ever had, and plan to keep it until it withers up and dies

I want a full body case that also covers the keyboard and the screen, like a plastic cover. Is there such a thing?

For those without a screen cover who touch the screen and use the stylus a lot, how durable is the screen?

I would think that fo full coverage you would be just as well off with some kind of pouch since you are covering the screen and keyboard. I use the clear plastic case Sprint sells that has open screen and keyboard for usefulness. It comes with a belt clip.

Personally, I think the key to keepiing the screen OK is remembering it is not a toy or $20 phone. It is a sensitive electronic device with some serious power but obviously some fragility

By the way let me clarify... I want a full-body case that I don't take the phone out of. I want to use the keyboard and screen through the case. The iPod Touch has a full-body case and still retains touch functionality. You can use clickwheels through silicone cases. So they do exist for other products, I want one for this one

If you haven't found what you're looking for check into it again. Verizon carries a hard shell case as well as a silicone one although neither covers the screen. Best to get a set of screen protectors.

I haven't found anything like that either. I got a form fitted case from Prima Cases for my sister's Centro. It is a leather skin with perfectly cut-out holes for every button. But the screen and the keyboard are exposed.
To solve that she just went ahead and bought a screen protector

The thinnest case on the market is the invisiShield. It is an ultra-thin film that covers all of the flat parts of your phone and is slightly tacky to the touch. Check out these links:

I hate bulky cases/protectors, so this really knocked my socks off when I got it installed. Check out the videos and customer testimonials. Every friend I have recommended it to has been pleased with the results on their device.

I would love to see something like the Krusell Classic Multidapt I had on the 700P.
BTW: Verizon does not recommend screen protectors. They say that one is incorporated in the design of the phone..

Bought a Krusell Cabriolet case , leather with multidapt clips. Really terrible for Krusell, which is usually high end quality cases. It doesn't fit well, gaps & bulges, and is almost impossible to put the phone in the case. It is too tight.
Got a $2 holster with my sync cradle from Everyday Source (Itrimming, accstation etc, all the same ebay vendor), and it is quite good, compact easy to take the phone out. I plan to try one of the two piece snap together leather ones, and then give up.....

I got the snap together case, and I like it. It fits perfectly, does NOT cover the keyboard and screen. A little difficult to take off to change a battery/reset.
It really looks good, nice finish. It is available in black, green or pink leather, many silcone flavors and a plain hardshell.

I've been looking for a full-body case w/ keyboard cover for the Centro as well. I've owned the Treo 700P, 700WX, 750 and 755P and for all of those models, Palm made silicone cases they called "Flexiskins". These cases covered the keyboard on those Treos too and were the best cases I had for any phone.
