Since both Acrobat reader and Realplayer are free to download anyway, buying the Discovery version doesn't really give you a lot that you can't get free!
Yes, it may save you a bit of time downloading and installing these programs, but I've generally found that officially distributed versions work better than distro-customised ones anyway.
As far as I can tell, the only thing that you get with Discovery that isn't free anyway is LinDVD. Is it worth buying the full version just for that one program? That depends how much you want that particular program.
