Windows Phone Thoughts: Your Must Have Application

It's fairly common on Pocket PC forums to find new users asking what applications are considered "must haves" for their new devices. Inevitably, a few people post long lists of their personal favorites and a few others write up semi-nasty notes saying "Use the search feature" or something else about how repetitive such threads are. I've often posted replies to such threads, and am always amused by how much overlap some lists have and how a few people have truly unique applications as their must have - dependent on their occupation. So my question this morning is this: What is your must have application. No more than 1 application per customer here - if you could only have 1 third-party app on your machine, what would it be and why? Feel free to elaborate on 1 or 2 "second must-have" options if your decision was close, but in the end, you must pick Number 1.

As for me? Well, I'll be happy to tell you my number 1 pick if you care to read on

My number 1 application has been, ever since I started in this platform, eWallet by Ilium Software. There are other programs that do the same job out there (Flexwallet & CodeWallet being the other two popular apps), however I've gotten very used to eWallet since starting with it in 2003. So why is this software essential and my number 1? Let's add up all the factors:

• My entire life is in my eWallet file. Current & past credit card numbers, bank info, registration codes, etc... all nicely encrypted
  
• It syncs to my desktop, and allows me to create secure passwords for sensitive websites without fear of forgetting them (It's a beautiful thing to create a 20 character password without fear)
  
• All my data is in 1 honest-to-goodness file. Maybe I'm old-fashion, but it's nice to have a file that you can back up without fearing that maybe some of your data was in a database or split up over multiple files. With eWallet (And it's competitors) you have peace of mind backup. As a plus, the files can be compacted - my eWallet file with literally hundreds of records takes up less than 500K
  
• Finally, it can export to plain text all of my info. I keep a plain-text printout of my passwords in a secure location (i.e. fireproof) that I update yearly. This process used to take quite awhile, now it's a simple click
  

So there's my number 1 must-have, now it's your turn to share. Remember, pick 1!
