You're free to do so. Just as I'm quite free to disagree.
It doesn't quite do everything. And to be fair; no platform at the moment does everything. Sadly, people tend to refuse to believe that... if it does everything, please show me how to make a Skype video call. That is important to me... and would mean that it actually does do everything.
And no... it doesn't mean that I'm advocating the iPhone 3G/3GS either. It doesn't even have a forward facing camera. But, via Fring... it can receive video at least. Oh... Fring's not on the N900 yet either. It does everything... right? That's very subjective to your uses it seems. I can name quite a few more things that it doesn't do for me. Thus... my aforesaid non-purchase.
And I'm a realist. I'm glad you enjoy your N900. Truly am happy for you.
But it's not about "seeing what I want to see"... I see some mighty big gaps that honestly... I'd rather not see. What's so wrong with that?
