Today I went to Sim Lim to buy more RAM for my 1-year old PC. The 1GB DDR2-800MHz costs only $39. In comparison, a lower-spec 1GB DDR2-533MHz in late-2006 costs $166.
I also bought an extra DVD writer with Lightscribe capability. Similarly, the latest DVD writer costs only $55, more than half the cost a year back. I have been contemplating for months whether to buy another writer because my current writer refuses to expire. In fact, my older writer, a Samsung CD-RW Combo Drive (DVD-ROM) is still alive and spinning on my backup PC.
It's scary to imagine how some products got so cheap over time, while others simply escalate beyond comprehension - like petrol. But this is simply the result of supply and demand.
