If you think so, please donate all your bitcoins to me and I will take good care of them, I assure you! And for the unconfirmed transactions, I believe they are mainly because of no or low fees. I have made a transaction today from my offline wallet and it went through smoothly as envisaged. I haven't faced any problem.

However, for the small amount the transaction fees is really high now which may discourage some small time earner to use bitcoin and look for other alternatives. But for high value transactions, even if the fees is higher, it will going through smoothly.
