Condensation in and on double glazing

However I'm concerned that after only 2 months there appears to be condensation on the inside of one of the glazed units in my bathroom, photo attached. So does the unit need replacing or the whole window? I wondered if water from the condensation could have weakened the rubber seal but it shouldn't have been able to get in anyway should it as the unit is supposed to be a vacuum  so is it a manufacturing fault?

It is difficult to tell from just a photo, but that looks like condensation on the outside outside of the double glazing unit, not condensation within the double glazing unit (between the panes). 
If it is condensation outside outside, that is a good sign of low heat escape.
If it is condensation within the double glazing unit (between the panes), that is a fault and a new unit is required.

Thank you KxMx

Yes bay window in bedroom with thermal lined curtains so it's inevitable. I'm not incapable of sponge and bucket job but not being a morning person I'd rather wizz round and not get chilled hands.

I'll start looking d'rekly

Oooh sponge and bucket, fancy, I usually use an old hand towel until it gets bad, then out comes the window vac!
