I just bought the Spyder 3 to go along with my Dell U2711. Unfortunately, I just noticed the Spyder 4 was released! The 4 Elite is $250, almost $80 more than the 3. The DataColor site says, "The fourth-generation sensor uses double-shielded filters for longer life and better performance. On average, accuracy and precision are improved by 26% and 19% respectively. "
I haven't opened the Spyder 3 Elite, yet. What kinds of folks should upgrade to the 4 for that super duper double shielded filters?
I'd go for the i1 Display Pro at $250. It tests well on a wide array of display types. I have some early hints that it might even read, straight out of the box, my wide gamut monitor BETTER than my $900 i1 Pro Spectrometer.
Maybe the Spyder4 will be amazing and the best yet but there are no reviews or tests regarding it yet, but the i1 Display Pro is already showing some extremely positive signs in early testing (see also the Dry Creek tests where in their initial test so far it has had less copy to copy variation than anything under $2500). Granted testing is still in the early stages for the i1 Display Pro so it remains to see how it will pan out in the long run.
I wouldn't at all be surprised if the S4 turns out to be better than the S3 though.
