Condensation, huh! what is it good for?... 

Condensation can come in various types & severity. Two neighbours can live in identical houses, but have a completely different experience of condensation (if at all). 
It's generally down to lifestyle & conditions. 
The creation of a lot of unchecked moisture can unfortunately lead to mould growth & damage to materials. 
Outside surface. 
 
When condensation is visible on the outside surface, this isn't a fault. Due to modern technology & recent improvements in double glazed sealed units the increased reduction of heat means that there is reduced thermal tramsission to the outside which dorsn't help warm the outer pane.
