I am one of the gazillion users of DB2 Express-C. And that's why I am really happy that (from now on I hope) there is a "light edition" of the DB2 Express-C download image. You can still download the full edition which features text search, the Control Center, languages other than English, and some other things I consider minor. For the most of us it means less to download with the next (or this) release, thus an even faster upgrade cycle.
And when your spouse asks what you are doing, remember to point out: It's the light edition now (and fat free).
