I see this mistake all the time. The units look similar, mA and mAh. Also I often see mW and mWh confused in the same way.
mAh is a unit of electric charge, like the coulomb. mAh is not a rate of charge, or a rate of energy transfer. It's basically an amount of electrons.
A battery might say how many mAh it can store and dispense. Combined with the voltage, this would tell you how much energy the battery has.
If you leave OpenMoko plugged in long enough you can have an arbitrary amount of mAh(until your battery is full anyhow). It has nothing to do with how fast it charges. Following your link i see you misread the article. It says mA.
Personally I'd rather know how many mW this thing charges at. The page you link doesn't mention the voltage, but USB is specified at 5 (4.75 to 5.25), so that makes a maximum of 1000mA*5V, or 1A*5V = 5 Watts or 5000mW. This is not very fast...
For the OpenMoko it's probably fine, the OpenMoko battery is probably not that big. For a big chunky laptop it would be terrible, it'd take maybe 4x as long to charge as discharge. You wouldn't be able to operate on battery power.
Think about it, if the laptop needs to have enough power to operate USB peripherals, it requires significantly more power than that to operate if it's to function with a few USB peripherals plugged in.
