Well, it really depends
what gamut they're talking about... they don't say I don't think.
I thought aRGB pretty much equals legacy NTSC. But whether a display is 95% or 120% of the NTSC gamut, it's a difference we're unlikely to notice very often, and either shows far more of the gamut than I've ever used before.
The only thing that turns me off on the 510 is the 15" size; oh, and I think the FHD option is out of stock presently, as I didn't find that option on the customization screen earlier tonight when I was on their site; tho I may be confusing that with the T510... hope not. In any case, Lenovo gives you a lot for the money, plus I get a bit more off with my wife's WorkingAdvantage EPP program. I could have swore I read a glowing review of the 510 a few hours ago. But searching my history the last day, I can't find it. odd.
Then you must have seen the W701 too? That's tempting. Even the W700 is sweet, either of them with an optional watcom tablet option in the palm rest and option for 2nd smaller display that slides out from the primary display; perfect to place the Lightroom image setting panels and use all the rez of the main screen for the image itself. But if I were to get it I probably wouldn't get the piggie-back screen.
I'd been strongly considering a Dell XPS 16, or Dell M17x, or even the M6500 (tho I don't get a discount on that) all w/RGB LED display. Downside however is they are also only TN displays, not IPS. And that's quickly rising in importance to me. With such a huge display, you can't help but span higher viewing angles looking from one side of the screen to the other than you would on a smaller screen. As TN just doesn't provide as uniform color, brightness, and contrast off-angle as IPS, the bigger the screen the more that is amplified. So I'm beginning to talk myself
into a HP 8740w with DreamColor 10-bit IPS display... 30-bits of color can show a billion colors.
It's pretty much
the premiere mobile workstation option right now for digital photo work and I'm having a hard time passing-up the 18% off offer anyone can get right now.
