There is no point to any of the alt-coins because they provide no value other than a means to make the owners of the exchanges rich and/or a means for late-comers to be able to get some bitcoins in a faster and easier fashion.
Unless an alt-coin is accepted for goods and services it has no value and cannot have value.
Time will tell whether other alt-currencies are valued or not. Right now, you can buy online hosting services using many alt-currencies through
www.Litehosting.org. More online merchants are starting to realize that if people are willing to pay you for one of these alt-currencies, it's MONEY! :-P
