Always one, used to be N95-3, 5800XM and now N900.
Need phone + good camera + good video recorder + email + web browser + GPS + games in one device

Before N900: just 1, iPhone
After N900: 2, N900 and iPhone (acting as mp3/video player)

lol - you're like Fox News... fair and impartial.

n900 -> work phone (2 months old)
- work calls, work presence, work email

HTC Touch -> personal phone (1 year old)
- personal calls, personal email
- winmo, sucks

iPod Touch -> personal podcast/video podcast player (3 years old)
- jailbroken 3.x?
- works fine for listening to podcasts and watching yesterday's news + geekbrief while working out
- reminds me why iPhone would suck if I had to live with it as my actual phone

So... three. Do I win a cookie?

Well, for me, I carry two, my N900 and my HTC Touch Pro2 (WinMo 6.5).

It is because N900 still don't have all the apps that I used daily on my HTC Touch Pro2.

I will always try my best to only used my N900 as primary phone,
the full web browsing experience compare to Opera brower, camera and music.

otherwise i will have to switch back to my HTC for stuff like full feature stocks apps, real easy to use gps navigation (TomTom/Igo), eWallet, vpn connection to my office, Youtube, my banking client, microsoft office mobile (free), mobile chinese learning apps, google traffic and games.

Hope Nokia store will at least like Andriod apps.

Just one fore me, the N900....I use it for everything.

Oh and I carry my keys and my wallet too.

Most of the time (I'm a mobile professional) I carry N900, E71 (for mail, Ovi Maps, Google Maps and in case the battery on the N900 runs out), Canon 5D Mk II (digital SLR), Sony PCM-M10 (digital audio recorder) and Sony S series walkman.

If not in work mode, just the N900 and maybe the Canon camera.

I carry just the N900. That's why I bought it so it could take care of all my needs: music, movies, camera and Internet.

I carry 3 phones lol.

1) Personal N900. Personal Emails and such.
2) PAYG N95 8Gb. Personal Business phone
3) Blackberry Curve 8900 - Work.

N900 + 3 more batters, as one Battery last 5-6 hours for me:-)

I carry three N900s.

(Kidding.) Just one N900.

I don't have any problem using Yahoo Mail or the media player, so I don't need two devices. I used to carry my N810 and a Palm Centro; the N900 far surpasses both of them combined. When I travel by train I take my Kindle with me, but I could do without it now that I learned about the Unswindle program, which allows me to read Kindle books on the N900.

What I really want is a Kindle-sized device in color that does everything the N900 does but has a detachable phone so I don't feel like I'm holding a large object up to my ear.Maybe I could carry the phone separately sometimes; then the Kindle-sized thing would be sort of a mobile docking station.
