The slow confirms are not a problem.
you're not considering it as a problem. that's okay. maybe you're not transacting so often hence you never really got the experience of waiting confirmation to arrive
To online transactions like purchasing online wherein it will take some time before they send you your items there is no problem. But when we use bitcoin in paying for a cup of coffee in a shop the long confirmation will be a big issue since some confirmation took a 2 to 3 hours time before it is completed. And so if you are a customer you will wait long before you can leave the shop. But another thing, if the shop owner is open minded after checking the blockchain you are allowed to go. But this issue of slow confirmation should not be left aside since big merchants see this as a problem.
