8GB is fine, the problem is all laptops are still shipped with 5400RPM harddrives. My mother bought a new $700 Inspiron from Dell, it's made of janky plastic and took 5 minutes to get to desktop and longer to do anything else. Replaced the 5400rpm drive with an SSD and it was plenty fast.
Oems are sabotaging themselves to get their customers to buy their $1200 laptops - which at that point people are instead buying macbooks.
