I use a droid bionic - I've bought into the system with 3 small batteries (2 day runtime) and 3 large batteries (4 day runtime) and purchased the laptop keyboard/hd display & charger for mine.  In addition to in house chargers, I put a car holder in my vehicle in the lower left corner of the windshield and hid the cables under a dash mat to the stereo.  The install was fairly simple since I could place the antenna outside and fish the thin cable through the hatchback, then put the flat panel booster behind the phone mount with the amp under a seat.
