Palm Tungsten E2.
Let me explain.
It's been four years since I wrote a review of the original Tungsten E. Three years since aggravation with the flaky T|E (bad switch) drove me to the short-lived SONY CLIE TJ-27. One year and nine months since the CLIE gasped its last and I reluctantly switched to the Tungsten E2 (same bad switch ):
...When the last of its styli was lost, then it would go to the junk drawer. I was ready for the end. I cursed each moment with its hell-spawned stylus - a demented offspring of a toothpick and needle. The earth itself had rebelled against that satanic tool -- there were no replacements anywhere. If I did not already despise SONY for their spyware scam, I would loathe them for that stylus.
And yet, I did not entirely welcome the end. I knew that the noble lineage of the US Robotics Pilot was fallow. True, the CLIE was a twisted shadow of its grandfather -- the Vx, and its great-grandfather -- the III, but what better options were there? The much disliked Tungsten E2? (Let us not speak of the father -- the ill-fated Tungsten E -- nor of the bastard IIIxe.)...
That E2, I swore, would be my last Palm device. Something better had to come along ...
But the iPhone isn't ready. It doesn't meet my minimum set of requirements and version 2 is at least four months away. Too long for my crashy T/E2 and it's too short battery life.
I thought I might buy an HP Windows Mobile, but nobody I trust can tolerate WM. Blackberry definitely, but that would foreclose an iPhone. Blackberry is my fallback option, and I'm not ready to give up yet.
That left Palm. I needed a stopgap that I was pretty sure would work with minimal pain. So I bought another E2.
At least my old chargers, SD card, and styli work with the new device.
I backed up my Palm and Outlook data  and just synced. Most everything works, except I have to resync my KeySuite office data to get my work life onboard .
So, really, it was pretty painless. The new E2 appears identical to the old one, and they both run Garnet 5.4.7. The new one is definitely faster, but I can't see why it should be. I doubt they have different CPUs.
I should be safe now until February. If iPhone progress is as slow as I expect it to be, I might continue to use the T/E2 as my work PDA.
 That's not easy of course, you have to track down the secret location of Outlook's data file: "C:\Documents and Settings\jfaughnan\Local Settings\Application Data\Microsoft\Outlook".
 I think even the best Palm of all time, the Vx (ok, so the i500 is a contender), had a bad switch. It tells you something important about Palm that they can't, or won't, spec a on/off switch that lasts two years.
 I've given up on any vendor ever delivering a product that would given me an integrated calendar/tasks/notes on the PDA and home, while synching only work related data at the office. It's not easy to do this and I'm the only customer who cares about this.
