That's because Bitcoin favours large payments. This is where it excels with its small fees and secure transactions. It's still hard to use for people on the move, who want to quickly grab a hot dog from a stand, but it's great if you're buying something in the internet. There are services, that don't even wait for the confirmation and immediately know the transaction has been made. For example I bought a steam game recently, and had the key on my mailbox in less than a minute.
