xtreme_db, yes, that link is the old Xenarc. It is also a biased test, as the camera was set to auto-white balance, and it locked to the display of the Lilliput, therefore making the Xenarc seem much "darker" and "yellower".
I have done a comparison of the newer Xenarc vs the Lilliput (unfortunately i had no carpc applications set up on the computer I was using) and I can tell you that the Xenarc is brighter.
Also, from using them in my car (in sunlight) i can also tell you that the Xenarc is better than the Lilliput. Due to the touchscreens, there is still glare, but the Xenarc is easier to read than the Lilliput.
The ONLY advantages i can tell you the Lilliput has are the following:
*Slightly* better colour representation - there is slightly less "banding" of colours on the Lilliput than the Xenarc. However, I honestly did not notice the difference until they were placed side-by-side, and only noticed this when I fired up a video.
For general use, if it's going to be in sunlight, I honestly recommend the Xenarc. The touchscreen has less glare (which is the most important factor) and the display is slightly brighter, and it is honestly easier to see during the day.
For purely/mainly videos, or if it is going in a place where it won't be near sun, then I recommend the Lilliput, mainly because in this situation, the glare from the touchscreen isn't as obvious, and the colour representation is slightly better.
