The answer to your question is that the mobile technology has evolved over the years.
A lot can happen in 8 years bro.

You can’t compare the specs of the Blackberry phone then with what we have in Samsung and Iphone presently.

Processor built and power, ram, rom, graphics (gpu), battery strength, screen size, camera pixel quality, network modems, ip68 certified water and dust resistance, Corning gorilla glass protection and what have you. And these new and sometimes exclusive specs like the Qualcomm snapdragon, Apple Bionic, Samsung exynos and not forgetting super amoled display cost money too.
