I have it and echo the comments made here. I use it almost daily. I also know there is more capability to explore. Right now, I look up cultural information and use the database for my collection. I bought it late last year and go the Orchid Board discount.
BTW, you can use it on 2 computers. So I have it on my desktop and my laptop. But, I still need to figure out how to share the My Plants files between the two.
