If there is one thing I really detest, it is RealPlayer. I haven’t installed it in ages, as it is the sort of nagware you want to avoid (and thus, as we call it, vote with our feet: just don’t use it).
The other day, I was sent an audio link that was Real Media stream, with an inclination to listen. So, I had a deep sigh and mentally decided to reboot into Windows 7 (or maybe even create a new virtual machine for it), install Real Player and run. Just before doing that, I clicked the link anyway, just for fun, and actually, to see if Ubuntu would offer me to install “Real Media Player for Linux”. To my surprise, Totem (the standard media player) opened and happily played the stream without complaint.
I am happier ever day with my Ubuntu setup
