If you're a mobile warrior, you may find yourself suddenly developing a case of RAM-envy. After all, 6GB, once considered an obscene amount of memory, is fast becoming typical thanks to Intel's Core i7 platform (the socket 1366 variety), and it's not unusual to see 12GB. Heck, some companies have even begun releasing 24GB kits. This begs the question, does your laptop's 4GB cut it anymore? We asked Crucial if they'd send us their 8GB DDR3-1066 SO-DIMM memory kit so we could answer this very question, and since they obliged, so will we.
