Perhaps this is a little more on topic for the discussion - do we have any idea of power consumption while providing internet over hotspot (so 4G and wifi interfaces active) in terms of what I would need to provide to the phone in order to keep it charged? I'm not asking for real, hard figures yet, I'm just looking for a consensus in terms of whats expected.

In relation to the previous "off topic" post (my apologies, I've owned an N900 for about a month - the idiosyncrasies are still being worked out on my end, my PwnPhone firmwares wifi is botched, meaning I have to hardline the USB for internet, but thats ok, cause I've gotta keep it charged) the VAIO Duo I'll be getting has the 1A USB3.0 charge port, specifically for fast charging devices like mobile phones. If power consumption of the Neo900 while in hotspot mode could be expected near that 1A, I'll be mighty happy, that'll mean I can run my phone indefinitely off the laptops extended battery - perfect for six hours worth of train trips, which I do regularly, where the old Macbook Air's battery dies after two hours (go figure).

It is a fact that for almost two hours of those six on the train, I don't have cellular reception, but thats a minor side issue I'll sort out with the Government Railways one day... *GSM-R tsk tsk*

So, I hope this is a little more on topic - again my apologies, I wasn't aware my issue had been debated to death, although I should've expected a software patch for it...

Many thanks!
