I was going thru some boxes and I pulled out a couple of vintage ones. Took the charging cables out, charged them up and it's working! What's cool about the Cassiopeia was the camera module add-on they offered but I didn't pick one up back in the day.
The HP 100LX was the best I’m my opinion.
I have to admit, there have been many excellent old school PDAs but IMHO the worst was the palm pilot with the graffiti nonsense. You had to write like a complete moron so the machine understood what you were trying to say.
Haha yeah, I remember the graffiti writing for sure!:O I don't know how many times I almost chucked the PDA out the window lol. I think the person that invented it was on acid or something?
Yeah...grooovy maaan! 
I never got into PDAs.
Now smart phones have pretty much replaced them, and of course I have one of those.
(Technically, I have 3 smart phones, but I only use one.)
I have an Imate jasjar somewhere
They were great but the batteries weren’t
Still have a Tungsten T5 for one remaining application. In use multiple times every day, got charged once a week. This machine is a miracle.
Cleaning out the garage a few months ago and found my old Sharp ZQ-3000, image from gizmodo
Still have my early 90’s data bank in a drawer somewhere https://watchcharts.com/listing/1659997/rare-vintage-casio-db-55w-db-55-50-data-bank-tele-memo-watch
I got a few of them, recall they were 6bux each (and bought probably 5 of ’em, figuring them to be disposable, as a lot of “cheap crap” stuff I’d get), but one lasted me forever. Forgot the brand, might’ve been Brother (yeah, as in the typewriters), that clamshelled together, display on one, keyboard on the other. Used to program in Iridium flares to beep the alarm minutes before so’s I could go out and look, etc.
Quite handy. Rolodex, clock/calendar, alarms, etc., pretty much a cellphone without the phone part.
nah been married too long.
oops i thought you meant Public Display of Affection
NEVER MIND

Just recently discarded my last old Palm. Had the camera module, the additional storage module, the math pak module and even a modem.
That all must have cost a fortune.
The math and storage modules were expensive, the storage module used a CF card. The other parts were purchased around end of sales as I used it for many years, no smart phones yet.
does a working tandy model 100 count?
OMG… I booted my Apple II the other day… I modded back then as well, so I placed Augat sockets under every chip on the motherboard… It got smoked a couple of times, but I could burn ROMS and had access to the other needed chips. I designed I/O boards for the darn thing.
I still have my Handspring 8MB; sold my Palm Tungsten E (false advertising as it was promised to be compatible with the WiFi module, but when it came out, it wasn’t compatible). I also owned the Sony Clié UX50; such a capable PDA with color screen, 360 degree rotating camera, expandable, and miniature laptop form factor. I regret selling it and it seems to be collectible now, appreciating in value.
Woah lots of peeps with classic PDA's and computers still out there! That's awesome and hope they still work great! It's quite satisfying to fire up those classics and go back to simpler times. That is if you still got the power cable.:D
My only regret was not being able to get a color Palm m130. It was quite popular back then.
In a box, behind some other boxes, I have my old Casio PV-S460, a Palm m500 and a Sharp Zaurus SL-5500.
