The Z22 is a bullet-proof device for securely saving your personal data, and full marks go to the team at PALM for its solid design. However, the AGE of the Z22, over the last decade, results in 3 problems - the batteries are all dying, and the delicate plastic touchscreen top layer is deteriorating - simply through AGE. When you say the touchscreen is "Broken", I would guess you mean that it does not respond to touch commands from the black plastic stylus that sits in the slot on the back, side, of the unit, when stored. I have never actually seen or heard of a screen that is physically "broken" - like the thousands of iPod, iPhone, Motorola RAZOR, and other touch screen phones that you see today, with cracks running across the broken GLASS. It "Could" happen that the glass screen under the top plastic touch layer is, actually "BROKEN", with the resulting cracks, but this is unlikely, since the trim around the screen is raised a HUGE distance, compared to today's touchscreens.
You can easily replace the screen for $9 if you wait for free shipping from CHINA, or, you can try a few tricks I learned on my Z22 over the years. I have put it in the freezer - which worked temporarily, heated it with a hair dryer - which worked temporarily, and peeled the top plastic layer off the screen- which worked temporarily. I have also replaced the screen with a new one. It is IMPERATIVE to put a hard plastic cover on the Z22 at all times- or you will eventually loose the screen again...

I hope this helps you to get your Z22 back up and running
