I have the ODM uniwill model. It is technically exactly the same
The screen you get with the alienware is like sony x-black or x-glass. However, some manufactureres are begining to offer the uniwill with this x-glass in now also! So absolutly NO reason to get a sentina, unless your verrrrrrry fasion consious. I still think my uniwill looks foxxy however.
Im from the UK and got my uniwill from here www.rockdirect.com
and they are now doing the x-glass as standard. I havnt seen any USA companies doing x-glass in it, but then again, i havnt been looking.
With alienware, you also get a lot of gimicks. You seem to pay quite a lot for these... Such as alienskin (a shell swapper app for windows?) alien spawn ( recovery disk?) and some personalized gubbins in the form of the user manual and 'top secret' box. Oh and the laptop shell is cool, but i woulndt pay nearly £300 for it..
Basicly its a luxury version of the rather nice uniwill
