Macbook Pro with SSD / HDD & Snow Leopard VS Lion Bootup Comparison

SSD bootup is twice as fast compared to HDD.whats more SSD makes your machine less likely to get slow for long period. and I strongly recommend keep using Snow Leopard(Mac OS X 10.6) if still Snow leopard on your Mac and you don’t need to use some features(ie iCloud) of Lion(Mac OS X 10.7).Some applications may be unstable for Lion.
