i doubt 4gb is enough this IMO is some what a cheap gimmick, though it will boost to a degree but still some apps which probably 90% of are going to be bigger then the 4gb really quick, unless you want only a hand full of apps in that area... im curious how will this manage with large files paired with small ones?
i can see this also being a complete disaster for any defrag program... how will it distinguish the 4gb or the ssd part with the hd part and properly defrag it?
IMO 30gb ssd is minimum and then if you have 200-600gb of HD will be fine, but 4gb? come on...
