Look UP Production

The rate at which computers are developing is just so fast that in the blink of an eye, the latest model you bought today might be obsolete in 2 months already! That is one fact that I have come to accept as just a few months ago, I bought a computer which was already fast with a 1 GB memory , but when I checked out this week, the latest ones in the market is already as high as 8GB! I though in just a few months the memory upgrade I would need just to keep up would already be this high? For that purpose I bought a laptop memory to upgrade my mac book and it turns out this Mac memory upgrade was so good as I can really see the difference in performance of that 4 GB versus the 1 GB I had back then.
