Myself and most all my coworkers are on 40%, and obviously tax evasion is not on anyone's mind. I think it comes down to your social environment and values.
If I were born and raised in the US, with all that anti-government and anti-tax rhetoric around me, I might feel similarly to the impassioned gentleman or lady above. Yet as it stands I am happy to pay for taxes as I see great value in them, and I would generally be happy for a tax rise if justified and needed.
Not the product itself, but there were only two features of Spotify around ~2010 that I used, which have both been removed:
* Set as Current Playlist: would allow me, with one action, to set the next playlist, but not interrupt the current song. Song would finish playing, then only song from selected playlist would follow (until I'd set a new 'Current Playlist' again).
* Empty Playlist: I used to have a plsylist called NULL with no songs in it. Combined with the Set as Current Playlist feature, this would allow me to, with one action and without waiting, let the current song finish, and then not have another one start (e.g. to go to bed, play a game, or to focus more intensely). Nowadays you cannot have an empty playlist anymore.
My 2008 MBP has a cool feature I miss: regardless of whether the laptop was o switched on or off, lid open or shut, you could press a little button on the left side and a number of LEDs would light up to indicate how much battery you had left.
