You see a lot of I'd
rather have the 7.8" version or I'd
rather have an even brighter screen, etc., and, well, yeah I guess... but that also completely ignores the cost side of the equation. Other options are going to cost a
lot more than the $300 extra that a
P4P+ costs and the Plus is by far the most cost effective way you're going to get into a pro-quality display. If money is no object then by all means get an
Inspire 2 and a 7.8" CrystalSky, but for bang-for-the-buck (one of the big pros of the
P4P series) the Plus model is hard to beat.
Also as mentioned above there are advantages beyond brightness/contrast, such as better stability and no unnecessary processes running in the background (very important for critical real-time apps such as DGI GO), no cables or setup, no hot cellphones and battery concerns, etc. Is the Plus screen absolutely essential? No, people have lived without it until now so I guess not. But it sure is nice.
