Navionics Chip

Does anyone use the Navionics Hotmaps Platinum chip? If so I have a couple of questions:
#1- How do you like it?
#2- Is it really worth the extra money versus the Premium?

I am upgrading from the 08 Premium chip because the 2009 and 2010 edition now has Lake Talquin with HD. Just trying to save some $$$.

Hey TNT I got the Platinum chip. I like the Platinum chip and had the 08 premium chip. Truth is as long as I got the HD maps I wanted would no spend the extra money probably if I was doing it again. The other little things I have not found real important.
Just my opinion.
