Seems highly unlikely... I think the time for those devices has come and gone, and won't return any time soon.
I would buy one, especially if it was tightly integrated with my PowerBook - dock and merge. I have a Handspring Visor Deluxe (PalmOS) but would replace it with the right handheld. The ideal machine will have (at least!):
MacPalmOS (stripped down MacOSX) so most applications supported and there can thus be great programmer support since you can develope for the iPalm or iBook or PowerBook or PowerMac and everything runs across the platform at what ever capability the hardware has.
MP3 + Recorder (Voice mic built in + Microphone line-in) - gotta have tunes!
Wi-Fi - of course.
Cellphone + 2.4GHz phone which works with Airports for internet calling. Since it's got Wi-Fi it could form local area networks and operate as a radio phone too. Useful on hikes or when working on the farm or fields.
Strong support for essencial apps like: iTunes, Addressbook, Safari, Mail, jNotes (Common Apple, Hire that guy!), iCal, iSpreadsheet, iWord, Preview, Calculator, WeatherMan, iData(base), etc. Strong merging support with desktop PowerMacs, iBooks and PowerBooks as well as iPalm to iPalm.
The screen needs to be ultra readable in bright sunlight, office conditions and in bedroom or the dark. It should be as easy to read as a small paperback book and folds to half that size for slipping in your pocket. This could be the eBook type machine that keeps getting reinvented. There are now a lot of great public domain books out there. This could spur a new must have application and industry making electronic publishing really take off.
It needs fantastic battery life. SolarSkin perhaps? Shake and charge? Induction charging? Recharge with USB/FW too. One thing to achieve the great battery life that Apple could do is have the processor crank _down_ in many steps so that it can dynamically adjust to the needs of the user. You don't need 1GHz to enter an email, lookup an addressread a novel or browse most web pages. A palm version doesn't need the high speed of the G5, nor its heat and power problems. The palm should also shut off higher power components to conserve battery. GPS and Wi-Fi could be shut down when not in use to save power just like spinning down the harddrive or dimming the screen.
It should work with wireless keyboards and mice. It should be able to be a tablet for another Mac.
No CD-ROM or DVD drive is necessary. Any movies or music is downloaded. Same for OS upgrades. Media is merely a medium.
Added bonus, snap two or more together and they join processors and displays forming a larger, more powerful unit. Place them next to your PowerMac, PowerBook or iBook and it merges with the bigger machine becoming a backedup resource of added storage, processing and display.
Infrared port for using it as a programmable remote with TV, VCR, DVD, stereo, etc. Open your garage door too?
DVD display of a stored movie would be cool if there is enough processing power.
Ideally I would like field replaceable standard batteries but if it had a SolarSkin and was water tight that would be even better.
It should be very small when folded. Thick credit card sized? Slip it into a wallet, purse or shirt pocket.
Most of all, it needs to be a real world rugged device. Drop it in the ocean, run it over, etc and it keeps on working. Ideally the case is totally sealed, it is wireless, there are no ports. Induction charging, wireless networking, bluetooth headset, keyboard, mouse, etc.
Built-in GPS and mapping software better than StreetAtlas would be a great extra for the Pro version.
There is lots of market for a really useful handheld device. Is this a PDA? A smart phone? A micro-miniturized Mac? It's all semantics - what matters is capabilities to do useful work. If something like the above comes out I'll buy several (family).
