Alienware is owned by dell now, and I will never own a dell computer. They work for about 6 months then everything breaks. I have never seen a problem free dell.
I'm on mine right now, it's fucking heaven. it's the perfect size/weight/speed for what I do, which is a lot of web dev, automation, and photoshop/design stuff
How does it perform using Photoshop? I had a non-pro 13.3 Macbook about a year ago, it didn't really live up to what I needed it to do.
Mac Book Air = Worthless if you do any photo or video. Also search google for macbook air wifi problems.
Go with a mac book pro
Is the screen big enough though? I usually have a lot of tool windows open (e.g. layers, history, paths, characters, info etc). It just seems like a really small work area to get used to.
Mac air have eye catching looks,but it is performance is not good as mac pro..
I'm a PC guy but bought one cause of the formfactor.
I like it. I don't play games or edit video. Can't say how it performs for those but for everything else it seems to work just fine.
I like the light weightness of it. No complaints.
Apple OS is sort of clunky compared to windows and seems to require a lot more clicks or memorization of hot keys. But it's usable.
