    Okay, if you don't like some of the absolutely stupid questions a newbie asks, then stop reading NOW...

    My wife and I are looking at the Evo. It will be the first touch screen either one of us has owned. My wife has long finger nails. Will she get by with touching the screen with her nail or will she need to actually use her finger? This could be a deal breaker for her. :eek:

    There's been interesting developments with this touchscreen. No one knows for sure yet, but the incredible just got turned down for fingernails on the touchscreen and the EVO is said to have the same touchscreen (from the same company, Atmel) as the incredible, so the EVO probably won't be able to have fingernail input.

    Her finger nails would do just fine, I would however put a screen protector to preserve the screen from scratches from a harder objects such as finger nails. :)

    i read in one of the threads here today...
    the EVO will have the new touch screen sensor tech. It will be able to handle: finger tips, finger nails, gloves, and a stylus. :D

    I have also heard that the EVO will have the same tempered glass technology as the Hero. Believe me when I say, the hero screen is one tough screen. very hard to scratch. Search youtube for Hero Screen test. :eek:

    hope this helps.. but remember.. it aint true till you see it in your hands!!!

    No, nails do not work because the screen requires the heat from your finger to recognize the touch.

    The Inc and the EVO have the same screen, and my Inc does not read stylus', fingernails, or fingers covered in gloves.

    Just read an article that says it does, but the phone in my hand says otherwise.

    Now, of course, I would be surprised (as well as many others) that the EVO actually have the maXTouch screen that has been demoed by Atmel...but I have a feeling that won't come true.

    Since when do touch screens require heat to sense touches?

    I don't know what planet you're from, but I could have sworn it was an electromagnetic charge displaced from your finger (skin) to the screen.

    yea capacative screens take the charge from your body (yes we all carry a current through our skin) and uses the to determine the location based on the coordinates of the current. it has nothing to do with heat and everything to do with electricity

    and Auto, can you PLEASSSE post the link to the article you read that said that? i would lvoe to read it

    You won't have to worry about scratching the EVO screen...it's glass and tough as balls.

    Glass is good as far as scratching, however drop the bugger on impact against asphalt and see Mr. Screen go bye-bye. Best bet is to get a case especially since the glass screen sits flush against the exterior body of the device, giving it an inch or half an inch of cushioning all around really wouldn't hurt.

    A 1/4 of an inch whatever floats your boat, what I meant is not to leave the screen or anything else fully exposed to hard surfaces. :rolleyes:

    I've never been a fan of cases...I guess I'm like Gekko in that respect.

    since its a capacitive screen you cant use your fingernail

    It is specifically designed to accept touches from fingernails on index fingers, but not others. Hopefully your wife wasn't planning on using other fingers.

    Do you know the advantage of capactive VS resistive?

    Resistive can use stylus/fingernail as well as touch but it is less accurate with touch. Also, it requires a thin layer of plastic over the screen which you may not really notice on the better devices but it makes the screen scratch easier and diminished the crispness and brightness.

    Most touch devices have moved to capacitive although there is still a place for resistive in some situations. I know in eastern countries where pen/stylus input is more widely used, there are probably more buyers for capacitive screens.

    ^ think you meant resistive at the end there ^

    the way it typically works is...

    RESISTIVE: plastic screens, and typically only allows ONE input at a time, there are multi-touch resistive screens but they are not TRUE multi-touch. the way they work around this is by picking up one input and then osilating between the two inputs very rapidly. it doesn't work well at all and is very buggy. this screen tech works by finding the location on the screen where pressure is applied. this is also why on resistive screens you can change the sensitivity of the screen, making it to where you lightly touch the screen it activates the touch OR change it to where you have to press more firmly to get the screen to register the touch.

    CAPACITIVE: these are much are much more accurate and do not require the constant re calibration usually associated with resistive screens, they work by locating a current on the screen, all of our body's carry an electrical charge and when we (our fingers) make contact with the screen, it detects that charge and locates it's position that way. it is much easier to track multiple touches on capacitive screen as one touch does not interfere with other touches like it would on a resistive screen. these screens however pick up your "touch" as soon as there is contact on the screen. there is now way to set a sensitivity level as there is either contact or no contact between you and the screen, no way to determine how hard that contact is.

    they each have their advantages and disadvantages but i capacative is defiantly newer tech and although it does not currently work with stylus and gloves it soon will thanks to atmel and their maxtouch technology (search youtube for videos).

    Isn't the EVO coming shipped with a Maxtouch?

    that is all speculation, it IS an ATMEL screen but nobody knows if it is the maxtouch or the screen the incredible uses (which could still be the maxtouch just not implemented to allow nails, stylus' and gloves to work)
