Summary: I think the lack of charger is a good thing. First of all they take unecessary desk space, and often feel cheap. While standard AA batteries are heavier than a Lithium-Ion battery (like the one in the MX Revolution), they are inifinitely superior. The Revolution's battery is not replaceable, quickly loses autonomy, and last a year and a half at best. Of course owning a charger with rechargeable NiMH AA batteries is a must (they are cheap, last several years, and can be found anywhere).
