It is installed, but it's turned off for long segments of the trip (I recently took it from LA to San Jose). I overheard one of the other passengers ask about it, and they were told by one of the Amtrak staff that there were restrictions on when they could turn it on due to some military facilities that the train passed near. I've read multiple accounts of other people being similarly disappointed in the Wi-Fi availability on that route in the one car that has it, and having been given various reasons for it.

It was a great trip, the scenery was wonderful, and the service was overall quite good, but the Wi-Fi was unavailable pretty much every time I tried it, so it may as well not have been there. Upgrades to the network availability and performance on Amtrak trains in general would be greatly appreciated; for some people, having good internet access during the trip makes the difference between taking the time to enjoy the train or taking a faster (but no cheaper) flight in order to minimize the time spent unable to communicate/work/whatever.

I think SafeDee was actually released a little before PortaBase, and several months before encryption support was added to PortaBase. Blowfish is a fairly common and simple algorithm, I doubt if there's any code in common between the apps in that respect (PortaBase uses an LGPL library called BeeCrypt in its encryption implementation, SafeDee probably uses a self-written implementation).

PortaBase does have a lot of extra features, but I can imagine that if you just want a password manager, something simpler may be desired. On the other hand, being able to encrypt a custom data table containing a variety of data types and then sort and filter the results can be pretty useful too (which is why I implemented file encryption in PortaBase instead of just using a separate password management program).

I have noticed a tendency to exclude PortaBase in reviews of Zaurus encryption software, I wonder if they just haven't noticed that it supports that...?
