Force-Feedback, Fly-By-Wire

[DHdragon]

Hello all,

I was wondering whether there is any sort of artificial force-feedback through the sidestick/control column of fly-by-wire aircraft such as Airbuses and the 777? Is there any difference in the force required to deflect the stick at low and high airspeeds?
If not, is this a drawback compared with non-fly-by-wire aircraft?
Do the forces felt through the control column in a non-fly-by-wire airliner help a pilot gain a feel for how the aircraft is flying, like they would in a light aircraft?

Apologies if these questions have been asked before, I have searched to no avail.

Thanks,
DHdragon
