Apple isn't going to make a PDA, but we'll probably see "Digital Lifestyle Devices" pick up more and more PDA functionality (al la the iPod). But if you want a PDA, the Newton is the way to go.

Since Apple hasn't made them in years, eBay's the only place you'll find them.
But don't just buy the cheapest Newton! Besides making sure that the Newton you bid on is in good working order, you need to consider the model you buy.
The Message Pad 2000 and 2100 were the last models and they have the best handwriting recognition, the best Newton OS (which is a fantastic OS), and the best features. They are however, bigger than your average PDA.
You should stay away from the earliest Newtons, like the Message Pad 100, because they have laughable handwriting recognition.
The one other Newton is the eMate. This was an education-only device and has a clamshell iBook-ish look. It has a keyboard as well as a stylus-controled screen. Its feature-set is comparable with the MP 2000 and 2100, but it's not really a PDA because of its size. Also, an eMate in good working order is incredibly hard to find.
Lastly, know that if you want to sync a Newton with a Mac produced in the last five years you'll need to shell out even more money for a "Legacy Port" adaptor. They aren't particularly cheap, though...
http://www.everchanging.com/ provides Newton-syncing software for OS X and more info.
This must sound like a lot of work for a PDA, but the Newton really is a fantastic device.
EDIT: Keyspan makes the kind of Serial Port adaptor you'll need. It's $79.
