I guess I am a minority, though I will say that XM was superior to Sirius and it hasn't ever been the same post merger...but I've been an XM subscriber since somewhere around 2001 or 2002. Sadly Sirius killed the most unique XM stations and many long time XM DJs lost their jobs post merger. The music type I generally listen (EDM) to is not available on other broadcast formats, and in my other cars that do leave the city streaming options just aren't practical...and sometimes I really don't want to have to pick what I am listening to and want someone to pick for me. Yes, Pandora or other Spotify radio may work for the latter...but data streaming isn't always practical, either due to intermittent data coverage or data cost. Though now that I will be actually commuting every day for the first time in 14 years I am sure I will experiment with streaming options a bit.
My i3 is very new so still under the trial, but I am wondering what I give up/risk if I add the i3 trial radio to my existing account...the upside is the trial includes streaming services and I've never paid for this on my other cars (was really annoying when they took that "included" service away post merger).
