Ah, here's Nokia's new XpressMusic 5610 and 5310 in the flesh -- well, in the plastic. Right away one can tell the 5310 is quite thin (about half the thickness of the 5610), yet manages to fit a 3.5mm headphone jack, while the 5610 is far thicker and only has the 2.5mm jack variety. Oook. Both feel acceptably sturdy, and we actually do kind of like the left-right rocker on the 5610; we've only had these S40 devices for a few hours, so it's a little early on yet, but we likes what we're seeing thus far. Check out the hands-on shots below.
