My recent wow moment was when I recorded a livestream interview from the internetradio with the recaller. I had forgotten about that app but it did the job very well. And I tried it with QSpot aswell...

The Fm transmitter, full pc like internet browser like no other phone, hardware qwerty keyboard, ability to play emulator games, how it is hackable so it can be personalised to individual user and their needs, 32gb internal memory for most of music collection videos photos and documents, tv out functionality on which we can watch not just videos but also photos web browsing playing games even doing presentations, after getting my n900 i hardly use my pc or laptop, flashing led indicator to let you know of missed calls ant recieved text messages with differrent colours,etc now best for last the community with loads of great people which help n900 user when they are stuck or having any problems help users persnolise their n900 in unimagined ways still making the n900 better smoother faster fun everyday by new tricks hacks scripts updates without the community this would have not been possible so thanks everyone on this community!!!

been late in posting but had my n900 from a year...and the 1st day wow was the multitasking...never seen anything like that before in any phone...feels like using an desktop..all my frends and relatives were just amazed to see the multitasking facility...

My 'WOW' moment came when my N900 was being replaced by Nokia Care and I had to use an N8 for a week.

It was, "Wow, this phone is **** compared to the N900"!

I'm so happy to have it back now and the N8 sold.

mine wow was the day when i bought it from pakistan ,imported to china,got it after 3 months or so ..and finally wow what a mind blowing machine ( amazing moment )

My N900 WOW! moments:

- When I first made a ssh connection to it.
- When I successfully modified several configuration files to what I wanted.
- When I installed the Power Kernel.
- When I realized that I can program this thing.
- When the first program I wrote for it ran successfully.

A pocket-sized Linux machine is awesome.

This little device got me looking computing much deeper. After 7 months since purchase I have installed Linux to all my devices and for some of my friends and my mother as well. Everyone has been surprised how awesome Linux is. Many friends still to convince, though.
I learn something new almost every day and am lovin' it.
So biggest 'wow' was the cure of addiction to Windows.

My "WOW" moments started when I turned on the screen (forgive me, I migrated from E65).

Downloading free apps (again, my last experience was the E65).

Able to do so many things on this 181gms of electronics.

WOW! the battery drained so fast!

Most recently, it was CuteTube!

Looking forward to more "WOW" moments!!!
