This is what i have heard, about the Nano:
Fragile
Scratches Easily
Poor Screen
Not Durable Enough
Countless Complaints and returns, just wait for another couple of months
Ipods are released in Canada come about 1 year later than US.
New Nanos are being released, with bigger screen, more durability, Camera.
And as a Final comment Just like most Electronic gizmos, they will just end up sitting somewhere in your house and collect dust after you get bored with it =\.
I personaly have 2 cassette players, 2 portable radios, 1 MP3 CD player (Sony Walkman), Several little computerized calenders with calculators. My own VCR. And they are all just sitting and doing nothing, some are even in my garage =\.
Now one thing i do like about the nano (no i don't own one, nor do i want one), is the size and it's sleekness.
Also this whole Ipod thing seems to be just a FAD (trend) almost like the gay old Tomogotchi that we all wanted as kids but thank god i din't get one LOL!.
Of course the Ipods are nice and can be used alot more compared to the tomogotchi, but still you'll prolly get bored of it or something.
Also I think and find that its rude to be walking around school or something or even talking to people white a little wire going to your ear, if you know what i mean. We are in a place of education and business and I for one don't think its socially acceptable. However if you at the gym or in the library, cycling outside or stuff like that it is socially acceptable

.
I go to the gym and i still don't use my Walkman, i used to but then i realized forget it, i just got bored with bringn it =\.
Well im done talking, sure there are gonna people critizing about this w/e.
Just FYI wait for the new NANo its gonna WAY better.
Thanks,
