    My new rMBP (With force touch) is pretty much always connected to charger.
    I am some times pull the charger for few hours.
    Is it healthy? (In normal situation I would pull out the battery when connected to charger but I can't)

    You should discharge and fully recharge maybe once a month or so. Otherwise you risk having shorter battery life in the future. Which may not be an issue if you never plan to use it anyway.

    Do you give any thought to your cell phone's battery? It uses the very same technology.

    Don't worry about it, use it however you please, you're not going to damage anything by leaving it plugged in. Pulling the battery when plugged into the wall for a Mac has been useless to do for the last 10 years or so. In fact, Macs throttle down to 50% power with no battery installed. Whoever's still doing that is living in the past. This isn't a NiCad or NiMH battery.

    No need to even think about it, just plug in when you want, leave plugged in for weeks on end if you desire, take on the go when you need, the battery is for Apple to worry about. Ever since I bought a MacBook Pro many years ago that had the sealed batteries, I quit caring about battery maintenance and health. Haven't had any issues at all.

    It will be an issue because if your battery completely dies then even when it's plugged in the system will automatically downclock the CPU and your system will run noticeably slower. This happened to me and that was what a Genius told me.
