First thought: your site gives a first impression of a shopping site with the scrolling devices across the top. But I don't think that is your intention.

Second thought: The site has three "primary" things: manage, share, discover. But none of these things appeal to me as stated. I think arriving at the site via a link should present the one primary use case that's most likely to hook me (probably "discover"? but then you're like a shopping site, so maybe "manage").

I'm concerned about "share"; people seem to be getting allergic to the word.

Beneath the fold, the first use case for "manage" is knowing when my warranties expire. I don't find this particularly compelling; I don't think I've ever (or maybe only once?) wondered whether a device I had was under warranty. Curious why you present that as the primary thing you can manage.
