This is my new Sony VAIO which is 4GB, win 7, blu-ray capable, HD, core i5, and 15.5 inches. My love, bought this thing at Costco recently because my Dell’s AC adapter quits working. Supposedly, I want the 14+ inches HP because it’s cute and I like the keyboard and all but that thing is core i3. There’s one HP also it’s about 17.5” with core i5 but then it’s a bit higher priced than Sony. So, I just chose this core i5 Sony VAIO for a change because I already have an HP in which my kid is the one using it.
