LCD Quality – Color Accuracy
Besides contrast ratio, brightness levels, and color gamuts, the other metric we like to compare on displays is color accuracy. As always, we use a DTP-94/Monaco Optix XR colorimeter with Monaco Optix XR Pro and ColorEyes Display Pro software. ColorEyes Display Pro almost always generates a better score on laptop LCDs than Monaco Optix XR Pro. Worth noting however is that the color gamut generated by Monaco Optix is usually larger. It seems that Monaco Optix requires a certain color gamut level before it functions optimally, which may be why the ASUS G2P is the only laptop we've tested so far that scores better under Monaco Optix.
The performance generated by the ASUS U2E LCD panel is decent, placing near the top of the charts for laptop LCD color accuracy. The only other ultraportable laptop we've reviewed recently is the Gateway E-155-C, which does achieve better color accuracy. However, we would take the higher luminance levels of the ASUS U2E over the slightly better color accuracy without hesitation.
While the first results compare color accuracy after calibration, it's important to remember that scores are much lower across the board prior to calibration. Here are the pre-and post-calibration detailed results for the ASUS U2E. Again, pretty much all of these results are surpassed by even the worst of the desktop LCDs we have tested. The ASUS U2E score slightly better than many other laptops prior to calibration, but with Delta E scores of 6.7 or higher that's something of a hollow victory.

I haven't used the VAIO TZ, but looking at the pictures they appear practically identical to the ASUS U2E in size and major features. ASUS includes 3GB of RAM where the latest VAIO units ship with 2GB, ASUS provides a mouse and carrying bag and Sony only does that on the top models, and ASUS has a 2-year warranty versus 1-year standard. On top of that the ASUS is priced a few hundred dollars lower for relatively equal specs (i.e. the same outside of the memory config, where ASUS has an extra 1GB). Sony does include T7600 and even T7700 CPUs, however, so the price difference more or less balances out.As an example, here's the http://www.newegg.com/Product/Product.aspx?Item=N8...">VAIO TZ equivalent of the ASUS U2E-A2B. It has a 12.5% faster CPU and comes with Sprint Mobile Broadband (but only a one-month trial, so who cares), with 2GB RAM. That competes with the http://www.zipzoomfly.com/jsp/ProductDetail.jsp?Pr...">ASUS U2E-A2B, which costs $100 less and includes an external 160GB USB HDD. The difference in price and features is quite small, but with the warranty I'd give the edge to the ASUS.

Wasn't there a variant of the U2E that had an external Sideshow display? I would have really liked to have seen that...Myrandex - Tuesday, April 15, 2008 - link
Why 2GB x 1 & 512MB x 1? Or even 2GB x 1 & 1GB x 1? To get dual channel performance, shouldn't they have two identicle sticks in there? 2GB x 2 ftw~!Jason

You can run dual channel with mismatched sticks on intel laptops. I've got 2gb + 512gb on my dell, and cpu-id tells me that it's running dual channel.They probably topped out at 3gb because they're shipping 32-bit vista and didn't want to confuse customers with 'missing' ram. You could add in your own 2gb stick for pretty cheap if you wanted to.

Note also that laptops running a 533FSB with DDR2-533 are already matched in bandwidth even in single channel mode. The extra bandwidth helps with IGP a bit, perhaps, but in a system like this the overall memory performance isn't nearly as critical as power requirements.bigdog1984 - Tuesday, April 15, 2008 - link
I was reading the article and im in need of some clarification on two points. Does the unit have micro-dvi or hdmi because the breakdown chart has hdmi and the review states dvi and how much ram is in the unit,,,chart says 3 review says 2.5JarredWalton - Tuesday, April 15, 2008 - link
Sorry - it's Micro-DVI. It looks the same as HDMI, but doesn't carry audio. At first I thought it was HDMI; forgot to update the table. As for the RAM, the systems are apparently supposed to come with 3GB, but the test unit shipped with 2.5GB (as stated on the bottom of page 9).ciparis - Tuesday, April 15, 2008 - link
Adding features that the MBA omits (like CD/DVD drives, replaceable batteries, and extra ports) is not "addressing shortcomings".It's making a different set of tradeoffs.
Whether that's a good thing will depend an awful lot on your needs and preferences.

Yes, needs and preference will always be a factor, but “shortcoming” does hold true. When some body is able to add features in relatively same size why wouldn’t it be a shortcoming? Even apple will release an update model to MBA with more ports, faster, etc…ciparis - Tuesday, April 15, 2008 - link
"Relatively" hints at the crux of the matter: it's not the same size, and it wouldn't be able to contain those items if it was. If you're pushing for absolute thinness, something has to go. If that's important to you, those are the trade-offs you make.Personally I consider having to lug things around that I don't need or want on my laptop most of the time to be drawbacks, but I wouldn't presume to call it a shortcoming of the Asus because have a clear understanding that that's my preference. It's a feature trade-off that makes sense to me but says nothing about what might make sense to the next guy.
