I'd say swedes should join the euro.
It ain't the prettiest looking currency, but with the whole EU participating in the euro, it'll be much easier to do business in the other EU countries and probably makes the whole EU area stronger economically.
It's quite nice when you don't have to convert between currencies within EU and the dollar is on a par with it, so it'll be also easy to count US billings

It didn't do much for the prices aside the normal inflation, except for some reason Finland didn't take 1 and 2 cent coins in use, but stores are selling stuff for prices like 4.97€, but then again, they did the same with FIM - 4.95 FIM and no 5 pennies existed.
Although 5 cents is six times the worth of it.
Takeda,
5 cents for a small candy?
Here the unwrapped candies are sold by the weight and none of the wrapped up candies cost were under 5 cents even prior to €.
It's been quite a long time from the last time when unwrapped candies were sold on per candy basis.
