Agentless Backup is Not a Myth
Of course, some potential users may also ask why in this age of relatively cheap pay-as-you-go cellular net access a SIM card slot was not included purely for mobile data access. It'd be a good question too.

Thankfully, the N810 features a 3.5mm headphone jack rather than a proprietary one
Nokia claims the battery will last up to four hours with the WLAN on and the screen alight, ten hours when just playing music, or 14 days when the N810 is on standby. In other words, depending on what you do with it anything from four hours to two weeks.
We charged ours up, made sure both the Wi-Fi receiver and Bluetooth was switched on and ran it for just shy of 30 hours before it packed in.
In that time we spent a few hours browsing the web, listened to an hour or two of our favourite internet radio station, Triple R, played some chess, did a bit of instant messaging, checked our email and watched about 30 minutes of Frontline. A balanced usage portfolio if you ask us.
Verdict
Taken at face value, Nokia's N810 not a bad box of tricks. For surfing the web, email and as an internet communication device it is a handy little gadget, while the operating system is easy to use, feature rich and robust. The relative abundance of software is another plus. But that lack of a SIM slot does niggle just a bit.

More Grunt == Less Battrey Life
Garry Byrne: The OQO 01+, although a nice device, is nearly twice as thick as the N810 and weighs nerly twice as much. The only thing the OQO has over the N810 is more storage out of the box and more poke in the CPU department - both coming at the cost of greatly decreased battery life. I'd only recommend a Windows UMPC is you *really* must run Windows apps.
I have a nokia 800
How many people reading the article didn't pick up on the fact that Nokia didn't intend this to be a phone? Why? Maybe it's because S60 (uck!) is too entrenched? Maybe because it avoids having to do many regional variants? Maybe because they want you to buy a phone with bluetooth to act as mobile data gateway?
I've never found a smartphone to be any good, TBH, either too big and bulky, or if usefully compact then is too small to have an adequate display - the N800's 800x480 display makes my Zaurus's 3.5" vga display seem a bit, well, stingy!
I also have zaurus 3100, & palm t3. I use the Zaurus for experimenting with Android and hacking TomTom to run on it!
The Palm is still in use as a PIM - *nothing* beats datebook5 (well, datebook6 does).
The N800 gets the most use
- the bright clear hi-res screen makes it fabulous for mobile web surfing, reading eBooks etc.
- the built in webcam works nicely with googletalk, I can video chat (when I want to be a sad geek) with my brother in california
- with USB host or bluetooth I can connect a nano keyboard if I wanted to enter lots of text
- with bluetooth (PAN) or wifi I can connect via any phone or any hotspot
- stereo speakers make it useful as a media player, built-in radio is a bonus; SDHC card can carry a hell of a lot of files!
- can play radio and TV streams - BBC News 24 live works well (but don't tell TV Licensing!)
paris - because she needs people to RTFA for her too.
and more...
I have an n800 - had it for a year or so now, and it has come on in leaps and bounds with each new firmware release. I mainly use it for portable IM (there's a version of pidgin that runs well on it - the full-screen virtual keyboard is excellent once you get used to it) - and ebook reading - using FBReader and Evince (FBReader used to be all I needed, but they seem to have reduced pdf compatibility - though there is a pdf reader in the standard build, I prefer a 3rd party app). If you can afford the n810, I would definitely go for that, mainly due to the hardware keyboard, but now that it has been superseded, the n800 should be coming down in price. For an inquisitive geek, there's no better gadget.
