Usb3.0 or usb2.0?

[blueeyed]

I am planning to buy a 16GB pendrive.which should i buy(usb3.0 or 2.0)?if i buy a usb2.0 flash drive will it be a waste in future?any way i dont have a usb 3.0 port now.I like sandisk cruzer blade 16gb very much due to its size,but available only in usb2.0. So please advice.

USB 2.0 would not go waste as USB 3.0 is backwards compatible
