Well for one thing, you don't have to stick to the recommended fee.  You can always just set a lower fee, and it'll take longer to get confirmed but will still go through, probably in a period with less demand (don't set it to nothing though, or it might not confirm).  So it's not really a commission.

Secondly, your transaction size was high because you accepted a lot of payments to your wallet, which is what the "small inputs" SFR10 mentioned means - that makes the fee for sending the transaction higher because it's made up of a lot of little bits of Bitcoin accumulated in your address.

If you send a larger payment, the fee shouldn't rise very significantly, and you'll end up with the fee being a much smaller proportion of the transaction, which is why Bitcoin is very convenient for large payments.
