Portable One UX vs. SX model?

Can someone explaind the differences in UX model vs SX?

I know the screens are different but otherwise, what are the fundamental differences in specs and target market. And specifically what are the weights of these models with various battery configuraitons? Thanks

 

The UX is a Clevo model, the M520N to be exact, while the SX is based on the Asus Z35F.

 

Thanks. Now what are the pros and cons of these. They seem very similar.

 

I can answer some of your questions based on the chioce I made on Friday.
I wanted a very portable laptop to replace my aging AMD desktop. I wanted a decent speed CPU with very good battery life, it need the old style PC card slot for my Verizon EVDO air card, and needed it to be rugged enough to carry when I travel (frequently). I have a older Toshiba w/ 15" screen that I take for work, so this was just for personal us. The build quality, (magnesium alloy), PC card slot and size of the UX convinced me it was the machine for me.
The SX has a little bigger screen (13.3 vs 12.1), but comes with an express slot, and the casing is carbon fiber (that would still suit me). It is limited to 1.5 gb memory, the UX can go to 2GB. Be aware, it does not come w/ an OS standard, could be a money saver if you have an extra copy. Other than that they can be configured with the same CPU, HD, and screen types).

Lastly, Ivan and Patrick at P1 are very helpful and know their products, they can also help you make a well informed decsion...K

 

That is helpful. I do not wish to discuss with P1 at this point and would prefer to get external views before asking the retailer questions.

What is the situation with the weight of these and what ral-life battery lifespan do you get for each weight?
