Toshiba X305-Q725: Quad-Core Gaming Notebook

Display Quality
The last area we want to test is the display quality. We have stated repeatedly that laptop LCDs pale in comparison to typical desktop LCDs, and the X305 doesn't break any new ground.
We test color accuracy using ColorEyes Display Pro, and we test with two different colorimeters, a DTP-94 and an i1 Display2. We test the laptops with both colorimeters using ColorEyes Display Pro, generating both LUT and Matrix color profiles. The reason we do this is that some displays respond better to LUT profiling while others work better with Matrix profiling. We select the best result out of the four tests for our color accuracy charts.
Besides the color accuracy, the generated profiles allow us to determine color gamut, using GamutVision. We use the matrix color profiles for gamut, as they usually have ~10% higher gamut volume. We will also report the maximum LCD brightness and contrast ratio.
Very few laptop displays score well in our LCD tests, and unfortunately the X305 LCD is no exception. Color gamut is only 40.72%, though calibrated delta E is better at 1.78. Other aspects of the display are better, with good black levels that help the X305 reach a contrast ratio of nearly 800:1. Again, it would be nice if the brightness levels allowed finer control, as the maximum brightness of 189 nits is good, but the next level of just 80 nits is a huge jump.
We're hopeful that with companies now offering higher color gamut LCDs that we'll see improvements in display quality from many more manufacturers. Color gamuts of over 100% are a great step in the right direction, but we still want to see improved color accuracy, and some users would appreciate better viewing angles - something that will require the use of non-TN panels.

I agree with the SFF notion except for a few points.The first point would be that no reputable mini-ITX motherboard manufacturer sells a motherboard with 16x PCI-e. Sure, you could always *attempt* to play games with the onboard graphics, but you're most likely going to be very disappointed.
Second point would be power usage if that is a concern ( which for me it can be since we're solar/wind power ). a SFF system built with care, and plenty of thought can still be a power house ( subjective ), and use ~50W without a beefy graphics card. However, you will find it very hard to beat a laptop in power usage just because of the LCD you have to hook up to that SFF system. A typical 19" WS LCD such as the one I have will use 23W all by its self which can put a damper on this aspect of the idea.
Another point would be cutting edge technology on SFF mini-ITX boards. I have yet to find a mini-ITX board of current that will address more than 4GB of RAM, a lot of them only have two DIMM slots. Let us not forget that a lot of graphics editors could use such a system ( I am one ), and even 4GB of RAM is cutting it close if you want to do any *real* image manipulation. The of course you have outdated chipsets on a lot of these boards that make them not even worth purchasing in my own personal opinion.
Anyhow, I suppose if you did not mind using a mATX board, you may be able to come out ahead on some of all of these issues ( plus many more I did not even address ). But if you're looking for a mini-ITX board that either uses laptop or desktop based CPU's . . . well, I just think that we're al going to be SOL for a long time to come yet.

Definately a white elephant. Not only that, wheres the subjective review vs a comparitive Dell XPS 1730?
