Well as I have Z1, which is quite big, I'm using TS mainly to receive notifications (using swapplink).
I'm receiving many emails (I'm using Z1 as my business phone) so it's great that I can see on my TS subject of email and decide what will I do.
I have sim card in TS and I use it all the time, when I'm alone in a car (and that's 6 hours per day )
I found TS quite practical for companion
BTW...from today, I'm using this app to help me save my battery power on TS and Z1
