Markets have sprung up that simply didn't exist before, and cellular fortunes have been made and lost.
But as OEMs and developers steel themselves for round two of the smartphone wars, it's hard to believe just how much the handheld console market has changed in five years, too.
By September 2006, the DS was hitting its stride. Nintendo had launched its well-received DS Lite hardware revision, third party support for the system was beginning to grow, and sales stood at 25 million globally.
Although the 3DS surpassed the none-too-shabby total of 19 million units recently, it's worth noting that Nintendo has been selling the console at a loss for much of its lifespan – making any comparison to the DS a little misleading.
Sony's first foray into handheld consoles also enjoyed brisk sales, particularly in Japan, where the tremendous appetite for Capcom's Monster Hunter series saw the PSP's popularity soar.
However, the PS Vita took six months to limp to a global sales total of 2.2 million, and Sony's figures for Q1 2012 show its state-of-the-art handheld being outsold more than two to one by the ageing PSP.
But despite all the doom and gloom, there are reasons to be cheerful. The 3DS's early woes were largely due to a death of quality software, a problem that Nintendo has solved almost single-handedly. Meanwhile, 'Cross Buy' gaming and strong third party support offer potential salvation for the Vita. Only time will tell, of course.
After all, a lot can change in five years.
