Actually that is exactly what I intended to do, but it's impossible to
compare "something" to "nothing". As I wrote, the ISP is somehow
blocking certain ICMP replies (not all of them) and I cannot compare if
there is nothing to compare to.

Yes - I should have mentioned that you can also get a desktop (which I
didn't need, but nice to know it's available).

I see your point, but in this case it does not help me for the

really relevant.

That is certainly a possibility, but since the packets and the replies

mAh is a measure of the capacity to deliver that voltage.
You know a battery doesn't last forever. If you suck a lot of current
out of it, it will empty sooner. If you suck only a little current, it
will last longer.
mAh is "milli Amp Hours", so a 1500 mAh cell can deliver 1500 mA for one
