Hi guys. I need some help narrowing down my choices for a PC laptop for my grandmother. I am a Mac person, so I'm not "up" on the PC market. Requirements: $500-$700 Windows 7 15-17" display >2GHz 4GB RAM or more (DDR3 preferable) Should I go intel? I know back when I used some PCs, I liked Athlon better. Has that changed? An SD card slot would be nice, too. Thanks!
