non-chemistry technology question

Sorry to "borrow" CCL's bandwidth, but I figure people in the
 audience might know the answer to my question...
 Is there a PocketPC solution which can do the following:
 1) Surf the internet via WiFi, with a browser which is
 useable by those with normal to aging vision.
 2) Download pictures via USB cable from a digital camera,
 or accept an SD/CF reader via USB so that pictures on one
 memory chip can be copied to another.
 3) Connect with typical presentation hardware, so that
 talks can be presented from the PocketPC (omitting the
 need of a laptop).
 4) Work with a Mac, transferring files, etc.
 Pointers and/or personal experience welcome!
 Thanks in advance!
