Nokia could have made better Symbian devices, and without the hardware limitations they certainly could have made 1st class Android devices.
No they couldn't; Symbian, as most of us realised, was past its sell-by date in 2007.
Like it or not, the iPhone changed everything. Nokia never reacted quick enough, and expected Symbian to keep selling on the basis of brand alone. In the past, Nokia have always done well through their philosophy of waiting for "new" technologies and hardware to mature, instead of being early adopters; what Nokia hadn't bargained for however, was that although the iPhone and its technology was brand new, because it was essentially built upon the success of the iPod and the iPod platform as a whole, the iPhone was already mature, stable and standardised.
Nokia had a mountain to climb to keep Symbian in the running, and though the brand alone maintained marketshare, the popularity of the iPod, and Apples marketing, not only managed to eat into Nokia's huge marketshare, but also left Nokia users feeling ripped-off, and out in the cold, once they saw their friends iPhones doing even more than they could with their Symbian devices, but most importantly, doing everything better.

after the launch of the original iPhone, for me, illustrates how bad Symbian is/was, and even though Nokia did try to improve it, the effort was complete half-arsed at best, and did not do anything to help devices compete with the iPhone - their primary competition. Just look how slow, awkward and incomplete Symbian looks in comparison to the iPhone. The internet browser is atrocious, and by this time, people were using the mobile internet on an hourly basis. It's only saving grace, was it's flash-support, but Nokia treated the browser as though it was still the early 2000's, and it was a niche thing to have or something. Yes, you can get Opera Mini and that would blow Safari out of the water... but I remember a friend with a 5800 - didn't have a clue about Opera Mini until I installed it for him - and to say he was made-up is an understatement. Previous to having Mini installed, he barely touched the Nokia browser - and most people don't/didn't know what Opera was. Ultimately, he upgraded to an iPhone after his miserable time with the 5800 and never looked back.
Anyone thinking that better, more powerful devices would have helped Symbian, is only kidding themselves. The N8 was a fantastic device by all accounts, it was the software that let it down, and more importantly, people would look at how fast, modern and fluent their friends iPhones were, and think what is this crap. The internet browser in Symbian in 2010, had barely changed since I had a Nokia 6600 - back in 2003. 7 years of innovation by Nokia, had led to nothing.
