I think they've pretty much nailed it from a mobile phone perspective - which you have to be a subscribing member to use. I like the 4.99 price plan, since I don't really listen to music on my phone much - but do tend ot whilst I'm working - either at work or at home. So I would deffinitely be inclinded to subscribe to that.
I can quite see why they would be struggling however to say "I suppose it's another example of today's something for nothing society." is absurd, free users have to listen to ads - if the ads are making enough money to cover the cost of playing the songs, Spotify need to look at how they can improve what they're earning from it. In my opinion it should be self sustaining.
My partner was really enthusiastic to make the switch, I was initially a little reserved about it due to the thought of baby crap going around the washing machine, it really makes little difference though.
I'm inclined to agree with you, I will be shopping around for flights a lot more now they're having another strike. Flying is risky enough without more, ridiculous, disruptions. If they keep striking, they're just going to end up out of jobs anyway by bankrupting the whole company. Its virtually there anyway.
