Jim Cramer thinks that the biggest announcement that Apple (AAPL - Get Report) made during its presentation was the Apple credit card. 

And, according to a Twitter poll that was run by TheStreet, people agree. Out of a couple of thousand people, 44% said that they were looking forward to the titanium card. 

However, Warren Buffett is taking the opposite side and said that he's not so sold on the services stream. 

He wrote that the analysts are going to have to perk up and pay attention to the card:

The analysts are going to have to start factoring the card into the valuation -- although they will do so kicking and screaming, because it's not in their models and they don't like to plug in new streams unless they are done by acquisition.

We don't know how many people are going to be lured into the 2% cash back that shows up instantly on your balance. We don't know how many people are instantly going to want 3% back on apps. We don't know how many will switch from Samsung to Apple to get these niggling gains. Except they aren't niggling gains to the working person.

Cramer further explained why he likes the credit card in his Facebook Live show.
