With all that said though, you really should stop misrepresenting Lenovo's "fix" for the supposed color issue. While that might have a minimal impact on battery life, it is a perfectly legitimate resolution. Essentially, it amounts to a color calibration by shifting intensity. People could probably do it themselves manually or with the aid of a few pieces of available software. Photographers have been doing it for years to color correct monitors. It also does not mean Lenovo has abandoned quality control or that they used cheap parts. Of all the companies/products you listed, in my experience, Lenovo and Microsoft have the best customer support. Dell, again, is a miserable experience with lost calls, part delays, and long holds on the phone to someone on the Indian subcontinent - that, BTW, is their premium XPS support. As a point of reference, when the XPS 12's screen failed on day 35 after purchase, it took 11 days for Dell to send the onsite technician for next day support. If you look at independent consumer complaint forums you will see that is not unique. HP and Toshiba are both acceptable for customer service but I have had reliability issues. I have not owned a Sony computer but they do also not appear to be the mark of quality they were at one time.
I'm not misrepresenting their fix. Their solution is to recalibrate the Lenovo Energy Manager so that it boosts up the yellow performance. I tried it out, comparing the default settings, their new settings, and a different Lenovo device and I found that the default settings are awful, the fix makes it better, but it's still bad compared to what it should be. Is it adequate enough? We don't know yet because Lenovo has given no information on the following variables:
1. What affect will it have on battery life for a machine that already doesn't have good battery life (you say it will be minimal, but I want to see benchmark tests and results);
2. If this fix is totally dependent on Lenovo's proprietary software, what happens if we change operating systems? Will they continue updating it when Windows 9 and 10 launch? If not, will the display revert back to puke green?
You say otherwise but I disagree: this is a huge mark on Lenovo's quality control record. There is just no way this screen should've gotten past preliminary testing let alone final quality control and shipment to retail. It's that noticeable. More frustrating is their response to the issue. You say they have great customer service. I don't think any company that lies to its customers is very great. This is a well-known problem: the thread on Lenovo's own page is up to 80 pages now. This problem is 23 days old but if you call the sales department, they'll lie to you and tell you there is no problem or that the problem has been fixed or that the problem was isolated to one shipment. All of that is untrue. If you call technical support they say that they've never heard of this problem, that this is the first call they've gotten about it, etc. I've called tech support 5 times and they all denied there was a problem. None of that is acceptable by any company. I'm just vocal because I'm really upset: I put off other purchases and waited months for this device, I was quite excited about it as it seemed perfect, and now there is this very noticeable problem that the company trying to sweep under the rug. It's been very frustrating.
Thank you for your input on the Dell XPS. I was considering the XPS 12, but look into those problems more now. I agree that the Surface Pro 2 is definitely the best built machine. I love the Surface line (I have the Surface RT). I was hoping for a larger screen (liked the Yoga 2 Pro's 13.3" one), though. We'll see. There are a lot of great devices out there this season but none of them completely pull away from the others. All have pros and cons.
