I have a ms works spreadsheet that I put together myself with all of our orchids on it. I use exel at work all the time. I use it to track what I have, when I bought it, where I bought it, price paid for it, when it blooms, and when I repotted it. Also keep track of the ones we've lost. waaah!
It's great to track them to see how your collection grows, and when they will bloom. My wife thinks it's a little weird, but I love keeping up with them. Good luck with yours.
