Nice simple gui, doesn't constantly phone home.
Oh man, but that thing was great for me. Not very much bigger than my Samsung Galaxy A50... well, probably two of them fashioned into a clam... Fit right in the pocket of a flannel shirt. I had been printing my schedule to my DayPlanner for years (I had a monster DayPlanner) then editing it on the road, and having to double post into my electric schedule in Outlook to print it out again tomorrow morning - The only way I could do it, as I needed Outlook for the interface to MSProject. Man I got that little REVO and it was not long but that DayPlanner hit the trash. Come home at night, throw it into it's tray and it synced to Outlook like friggin magic.
It was frustrating too though. Technically it could get to internet, but it required a special cord to tie it to my cell, and only European cells were supported. Drove me crazy to be so close to doing it all, but so far away. I didn't really get all the way there till smartphones. Like, maybe 3 years ago.
Now, finally, email anywhere I go, schedule syncs to all devices... I really want for nothing except tasking which sucks as I am task oriented. But even that is getting better.
One thing I would miss are AI assistants. I do use the shit out of those. "Hey siri call my wife on speaker". Just so fast and easy.
Yeah... Giggles and me have a love-hate thing going on. She gets pissed at me for being such a redneck - Half the time she doesn't understand a dang thing I am saying. I keep saying I need an AI that has two first names and calls me sugar.
But I would miss her if she weren't there. And NAV. I would seriously miss navigation. And the PIM thing I said before. And instant internet and email pretty much anywhere on the valley floor. And even danged ol text, which I hate most the time. I harrumph a lot about going back to a flip phone, but I confess, I don't think I ever will.
