Panasonic R3 Review the Panasonic R3, a machine so well put-together that I actually considered buying one for my own personal use, and if it didn't cost twice that of my budget (importers are selling it for around $2800 for a fully-spec'd out unit), I probably would have. What makes the R3 the hands-down best sub-notebook I've ever used? Well, for starters, it actually usable.
