Yeah, a fluorescent tube might give some power. I just measured the light coming off one in a reasonably bright room with an insolation meter. About 75 cm from the light, we were reading less than 10 W/m^2 (we might see 1300 W/m^2 outside on a sunny day here). If these panels are 18% efficient (pretty good for a solar panel), we'll see under 2 Watts per square meter of panel. Just 8 m^2 of panels will run a desk lamp with a CFL, saving $2.25 a year if it is on 2000hrs a year and electricity is $0.08/kWh. If 8m^2 of panel costs just $1000 (very low estimate), we have a payback time of just under 450 years.
(back of napkin calculations, don't rely on these numbers)
The N9 has arrived. What we can say from our first experience is that we're in the presence of a fantastically designed device with a gorgeous AMOLED screen and some highly responsive performance.

@chemix +1 for bothering.
