<p>As the owner of a UL30A (13" version of the UL50), I do not recommend it if you're planning on doing CAD. It's a brilliant light+mobile laptop, and can photoshop just fine, but I'm not confident in how it'll hold up with CAD.</p>
<p>The Envy series seem pretty popular right now, if you're interested. If you want a balance of performance and mobility, they'd actually be my first recommendation. If not, how about the Asus U35JC/U45JC (just released)? It has a Core i3 CPU with a 310M graphics chip, if I remember right, with nVidia Optimus and 8 hour battery lives. If you want something more powerful, the Asus G60 or G73 series will suit you fine as well.</p>
What kind of battery life are you looking for? Mine gets a beautiful 1 hour, while the Asus you listed gets 3. The Apple laptops can pull like 10 hours though!
<p>That's because they use a weaker GPU, and they only get 5-7 hours (depending on Core 2 or i7), not the advertised 10.</p>
I have the exact same question!
I've been looking at computers incredibly similar to those, I don't want a Mac, and I'd like decent battery life!
<p>Again, I'd like to suggest the Asus U35JC/U45JC. The U35 is 13.3", and the U45 is 14.1". They both have the Core i3 CPU with an nVidia 310M graphics chip and Optimus technology, and has an actual battery life of 8-9 hours on the integrated GPU. Pretty great laptop :)</p>
