I realize adding driver only information and whether they need updating is basically adding a whole new program to the base program; but for the price I'd expect to see such extra's. :)
all of the programs I know of that enable the user to ee whether their drivers need updating have a yearly subscription. If you added such a tool at no or little extra cost, with no annual subscription it would justify many home users purchasing a licence as after several years it would have paid for itself with respect to not having to pay annual subscriptions for such a service. I'm sure you would get many takers simply because of this extra tool. I certainly would consider buying an upgradeable licence. :)
