Hover states are everywhere.A I don't think I've ever written a stylesheet or designed a site without putting a significant amount of thought into how they should behave. As users, we've been conditioned to rely on hovers states to trigger changes in link color, reveal action items, and navigate through multiple tiers of a drop-down menu.
Fascinating how mobile devices are forcing designers to rethink their decisions and rethink aobest practices.a One thing I dislike is the current trend of making changes on a per-device basis, because it needlessly complicates an already overly-complicated process. Do point-and-click devices need hover? I don't think so-if mobile/touch is one of your target markets, just do without it.
