The computer is really developing so fast that in just a few months, the latest model you bought today might be obsolete already! That is one fact that I have come to accept as just 7 months ago, I bought a computer which was already fast with 1 GB ram, but when I checked out yesterday, the memory that is in demand is already 4 GB! Wow, I though in just a few months the memory upgrade I would need to be up to date was already this high? SO anyway I bought a laptop memory to upgrade my mac book and it turns out this Apple memory upgrade was so good and was so fast already that it was amazing how fast my laptop performed while testing it a few hours ago! The wonders of science never ceases to amaze me.
