How do you react when you see a new flavor, type or upgrade to an existing product at the store?

For example, say you like Doritos. You’re walking down the chip aisle at the grocery store and you see a brand new flavor (Loaded Pepperoni Pizza~). Do you:

A) Since they’re new, you’d love to give them a try and grab a bag right away
B) Maybe wait on them and see what other people think or if they’ll stick around for a while
C) Don’t bother with them, you like the original flavors and are sticking to them

That’s only a specific example. In general, with new products, what do you think about them? Are you excited and like to try new things or do you wait on them or do you not bother and stick with the original? Do you think some companies produce new type of their product too often or not enough?

Another example would be a new iPhone.

And if you’d like, give an example of something new that you recently tried. How was the experience?

Remember, I am talking about new types of existing products!
