Hi guys, My Question is The iPad Air has the same ram as the iPad 4. I wonder how can it be faster than its predecessors (iPad 2, the new iPad, iPad 4)? I currently own an iPad 2 and my bigger bro has an iPad Air. Comparing the two, I could notice a significant difference in speed of the devices. By a total contrast, while I was going through posts about Macbook pro upgrade options. I got so many recommends toward upgrading the Ram not the CPU of the Macbook. Therefore, I'm kind of confused here. Is it the Ram that make the device runs faster or is it the CPU doing the the job (as I already knew that the iPad Air use the A7 chipset) Regardless, have any of you guys noticed that every time a new Apple product came out, the previous product starts getting slow and laggy? Is this some kind of marketing trick or something else? I'm really curious about this, plz help me understand. Thanks ^_^!
