Recently replaced my 9 and half year old Acer laptop with a brand new Toshiba i5. No, I was not using this old thing regularly anymore, just a desktop. Just like in this review of the Acer Ultrabook I was a bit disappointed with the 15.6 LED screen, definitely much better than the old Acer, but still poor viewing angles, especially vertically. But with an i5 2410M CPU (maybe not he latest generation), 640Gb HDD, an extra 4Gb RAM, 8Gb in total, 2Gb dedicated NVIDIA Geforce 525M Graphics, a BlueRay reader/writer al for R7.1K ,I am still happy. By the way that Acer hardware still works, only had once a silly temporary issue with the screen backlighting, that magically restored itself.
I got myself the Asus Zenbook Prime, 2nd generation and are very pleased with it. It has the highest resolution screen on the market for ultrabooks. It looks much like a MacBook Air, just looks nicer and runs Windows. It does not have a DVD drive but who uses that anyway? It just adds unnecessary bulk and I would not be interested in an Ultrabook if it has a CD drive.
