For pure laser printed text output that should be easy.
It is straight b&w so, yes; 600 vs 300 is clearly discernible.
As you pointed out, low-contrast and color output is entirely different; good anti-aliasing and sub-pixel addressing makes a bigger difference that raw resolution. Especially for real-world text displays.
(Microsoft proved that ten years ago when they introduced Cleartype and MSReader with qvga 4in displays.)
The value of these new LG displays is not in their pixel density or text sharpness: the value is the same as 1080p HDTV displays, the ability to display fullHD video *without* rescaling. That is pretty much the same reason Apple chose QuadXGA as the resolution for the new iPad; being able to simply and cheaply (in graphics power terms) scale iPad graphic resources and video through pixel doubling instead of a pricey video scaling chip.
Device designers considering these new displays will have a new trade-off option: use a lower resolution and cheaper display with video scaling in software (eating up CPU/GPU cycles) or a dedicated scaler chip, or go with the newer and pricier panel. Depending on the product's positioning, the FullHD panel may be a better choice on the merits.
And of course, they get to hype the (marginal) "benefits" of the higher pixel density.
