One of the first experiments I tried when I got my Nokia E70 was to install the Raccoon webserver application. The stuff you can do is quite astounding and really made me see the potential of a mobile web server for interaction over the internet, kinda like the first time you gain root on the IT.

For me the N800 and the Nokia N75 are pretty much all I need as far as mobile access is concerned. My breakdown for uses match up with the original poster pretty much perfectly.
- Small(ish) size
- 3G UMTS 850/1900 and Quad band Edge/GSM
- Same charger as N800
- I like to use the 2 megapixel camera and the music player on the N75, its just too handy to have a music player already in hand all the time.

- For PIM and email I use Mail2web.com and this is synced via Activesync (Push email) on my N75 for when I need to read email offline and when on the N800 I use Outlook Web Access which fits really nicely on the 800 pixel widescreen. This way whether I use my cell or the N800 all my calendar, contacts and email are in sync.
- Mobile Video I use the N800 obviously.
- GPS I have a Holux GPSslim 240 and since I don't have a car (I live in NYC) I prefer it to having another thing to hog the battery.
- Stowaway Bluetooth Keyboard for when I need to 'work'.

Since getting the IT I have moved away from my previous stance of the convergence device being king, N95's, HTC Tytn's, E90's etc. The N75 and the N800 are great complements to each other.

As mentioned in another thread here, the Ideal Companion Phone would have a full keyboard (such as on the E70 or E61) that could be used by the tablets.

EDIT: my brain kept running after i posted.

Imagine the companion phone is styled like the next tablet, and even docks with it at the bottom. Suddenly you have everything you want in a very compact package. Ideally, you have an E70 form factor: unfold it to expose full keyboard, and plug into a port at the bottom of the tablet (the connection would allow some degree of swiveling along the bottom axis). The companion phone's LCD becomes available for status messages, etc.

Take speculation further: the next tablet could have a docking station port at its top (as we've discussed elsewhere). This is replicated on the companion phone; there could even be a way to dock the companion phone and then connect the tablet in an alternate way to the docking station (ie, the top of the dock). The dock port is a buss that any peripheral can access, daisy-chain style.

Ooo... gotta shut up now.

Maybe its because I forced myself but I can use the onscreen keyboard at about 90% of the speed that I could use my E70 keyboard and about the same speed as my Blackberry 7100. Therefore I really only need a full keyboard when I want to post a blog, write a doc or send long email. You need a fullsize for that not a thumb board.

Understood, but that won't be true for everyone, and I was just exploring possibilities...

I want something like this:

as my companion phone. Except it should have working voice dialing, a cradle in the watch for the earpiece (preferrably a double stereo version), be a lot less "smart" (no colour screen, only basic phone functions), auto-connect with my N800 and, most importantly, not cost upward of USD 800.

Actually being available to the general public would be a huge plus as well...

I've said this in another post, but I would pay good money for software to use my E70 as a bluetooth keyboard with my N800. Apparently, the E70 supports the HID profile, so my guess would be that it wouldn't be too hard to develop. I really can't stand typing on the N800...mostly because the N800 ignores 1 out of every 10 keypresses or so, even though I get an audible "click". I avoid typing on it as much as possible. Using XTerm with the onscreen keyboard is simply torture!

The E70's keyboard is phenomenal...the tactile feedback is excellent and I can type while hardly ever looking at the keys. My only gripe is that Nokia swapped the position of some common characters from the standard qwerty keyboard layout, which drives me nuts. (What satist at Nokia made the decision to put the double quote as shift-2, and the @ symbol as shift-' ? Ridiculous.)

I also wouldn't mind being able to form an ad-hoc wifi network between the two devices for file transfers. I could dump a bunch of photos and movies directly to my N800 quickly, as opposed to slow Bluetooth or using an intermediary computer to mount their external cards.

I think the best solution would be to put an UMTS-SD card on the N800 and to write a software to call with it.

In fact, the huge screen of the N800 could make us use this device like an iPhone. Isn't it?

Please don't ever use the words "N800" "iPhone" and "like" in the same sentence again.

At least not without "not" and "absolutely" in that same sentence...

Sorry. I try to write that sentence better:

"The huge screen of the N800 has enough space to show a large phone dial. Why not to write a software that could make N800 able to phone this way?"

P.S. My English is not very well, so I have to use expressions like "x like y" to tell some ideas. When I wrote "like an iPhone" I intended "with a large touchscreen phone dial". I could say also "like the LG Prada phone", buy I think the iPhone is best known!

:-)

I was joking...
