N800: 144 × 75 × 13 (/18) mm
N900: 110.9 × 59.8 × 18 mm

Not even N97 mini is thinner than N800. And it's got "mini" in it's name.
N800 is very slim at the end.

If you mean by the width, the N800 is definitely wider than the N900.
N900's very pocketable. To put N800 in pocket, you need majorly baggy jeans.

Haha I don't like wearing jeans (the fabric irritates me and it bothers me when I touch it). Most of my pants can easily fit the n800 into a pocket so the n900 will fit easily then.

@Laughing Man: Lol, something like this perhaps?



Seriously tho..

I also think the N800 dimension is ok. People adapt quickly with these sort of things anyways.. either they leave the device if it bothers them so much, or they can cope with bigger pants, clip\holsters, manpurse () or whatever.

Haha manpurses.. (I had a friend in college who used plastic bags as man purses). But nah, my pants aren't that baggy =P.

But I could fit my laptop in there if I had that lol.
