Needs a memory upgrade soon

My Mac memory when I bought my laptop I clearly remember was 1 GB and that time, it was already to of the line and to own one with 1 GB was clearly owning some real fast computer. But now, just a mere 6 months later, I think I am in desperate need of a memory upgrade as some of the programs I need to run in my laptop would frequently stall and hang up and the diagnostics done on my computer simply showed I needed more laptop memory which was quite surprising as in just a short span of time, my 1 GB was nearly obsolete already. I guess it is hard to catch up to technology these days but I guess I have no choice but to log online to www.memoryupgrade.pro and buy a new 2 GB memory there.
