Girls, girls, you're all pretty.
Seriously though.
No one knows for sure the level of compatibility with these applications, to be honest. I know my Ativ has a wacom and pressure sensitivity doesn't work in some software, including SAI, for instance.
Many devices require tweaks and changes by the end user to fully work. A few reviews from pre-release units with unfinished software do not prove anything.
As far as this argument concerns, I hope I can clarify, so let me know if I'm off:
KevC4D's point is seemingly that once shouldn't judge a book by its cover. So what? It's got NTrig. Doesn't mean it's bad. They [KevC4D] are seemingly even a professional, which adds credibility to what they say. There's a good chance the Pro 3 will work fine for professionals of all caliber amongst many programs.
Reflexx's point is that one shouldn't buy before knowing of its compatibility. Research before you buy. Wacom is tried and true, with years of experience. WinTab is a popular, albeit outdated, solution. As such, professionals should air on a side of caution.
However, both of you, no offense, seem to be unable to see the forest through the trees. You have taken your points to extremes and no longer seem to be to be making headway in the topic.
Lastly, I will add that, compatible or not, sometimes change is needed. What I mean by that is that there are many options on the market. However, what I've seen is that the most popular options are sometimes also behind. For instance, I've talked to and seen posted online a number of artists using SAI, and getting excited over new features, that upon looking, software such as ArtRage already has and has had for a bit. The popular options are sometimes the most behind in advancements. Sometimes, users need to be pushed by new technology to make the change to better alternatives. Whether this applies to the pro 3 has yet to be shown. But it's to be considered.
