i think the next step is to be able to raise and lower the lights as the girls enter and move about the room, allowing them to get even closer.
I've never understood the need to have a phone last weeks on a single charge.
For me, usually when I'm having a really long day, it corresponds with using my phone a lot. Like a day stuck in the emergency room for a family member. I'd already had a full day's use of the phone, then spent the next 8 hours having to call family and friends about what was going on. My phone had already gotten normal use that day, so it was at about 30% when I left for the hospital. The brief charge it got on the way took it to about 40%, but with all the calls, texts, etc. by the time we were done the phone had been dead for 3 hours. I've taken to stashing a USB battery charger in the car. It stays plugged in, and can throw a full charge into my phone when needed.
are you in management?
