Well...
I think ...personally ...since the great innovations ...
ie : (and I hate to say it of this first one ...but it does merit the mention...)
the first iphone...
the palm pilot..
the original blackberry ..
and of course the nokia original NIT's... the nxx0 line...
(I'm sure I am missing one or two...)

Since then...
well...
It has been stagnation ...or de-evolution...or regression...since then frankly.

Sure we have 16gb + ram with stupidamountsof storage ,octocore , water cooled, no edge, swiping....

But I don't really see much in "actual" innovation....
everything is dominated now by social media apps...
and the best we see in advancement is the expected...
with a small "extra" here or there...with every successive iteration .
it is a gamble ...a huge risk to change...or rather "attempt" to change the entire playing field of the game...
and that means you have to anticipate what people will want or need.
And I think the companies cannot do that any longer...nor are willing to take the monumental risks involved ...

Nowadays...as we have seen...if a company doesn't come out with an expected functional released device...then that can sink the company.
the samsungs that were catching fire ...almost sunk the company.
the BB's losing their battle with governments to retain the security features with their encrypted communications for their endusers almost sunk them...and it altered the company drastically since.
I could go on..

It is dangerous for a company to simply come out with a new model that ends up being a failure...in whatever way......they may not recover...
So forget about taking huge innovative risks...
It is dangerous for them to do less... or more... than what is expected of them ...

I don't think much good has really happened since the n900...and that was simply adding telephony to the NIT mix..
A good jump for linux phones...
But..
Hardly a huge innovative leap...
all the ground work was already laid by the 770, n800 and n810...

the n900 was merely the next logical step forward...
no huge leap though.

So looking at the playing field ...it is a bunch of companies too scared to change the game for fearing defeat if they fail...
so now they just shuffle along making minute changes along the way...
