And that's the idea behind the virtual world or web data base. From the reported location, orientation, and direction of the device a calculation would be made and the display would be relative. No need for laser range finders.
In fact the application could "know" if it is daylight or night time, if it is fair, overcast, or raining.

Perhaps I'm missing something. If there's a database of 'augmented' objects, the tablet knows its position and orientation in this augmented space, and the tablet has access to that database, then the object the tablet is pointing towards can be found using only an algorithm and no additional hardware. This is true weather or not there are multiple objects in front of the tablet.
For example ray-tracers use a such an algorithm to determine which surface a cast ray intersects with. I suspect something similar could be done with more simple targets (eg. a large cuboid for a building), and limiting the intersect-able objects based on their relative position.
I may be misinterpreting the discussion, though. I admit, I've only read the last two posts!
YARR!

But, as said, if it's just 'hey what's this building I'm next to', you're good to go even with N810 class hardware.

15 years ago very few places were horizontally mapped.
...and yo ho CC I believe you're on the right track... It wouldn't be hard for a country club to 3D map its grounds, provide golf carts with displays, GPS, and wireless connections to their network. Based on the golf carts orientation, the display could provide a whole bunch of usefull info to the golfer. I wouldn't be supprised if this was already available at places like Pebble Beach
For that matter, the same could be done in large resorts or theme parks and with a device provided to guests for use while there.

I would like to see a device that looks similar to this.

I haven't read the thread, but had a thought I wanted to put out there and this seems to be the right place.
Wish item for the N900 or future devices: Video out.
I just got a HD tv and went through the devices in my house for compatability. I've dismissed the video out on digial cameras (and still doubt i'll bother to connect a camera EVER). But then I looked at the N800 and wished I could connect not only internet but MP4 playback device. Perhaps this would have very narrow appeal.*
Then the today I find this device 'Neuros digital recorder' (versions have been around a while and discussed here before). It redoubled my wish to be able to connect my N800 (and now for video in). Now that I type this, I seem to recall archos had a docking station for recording. Either way for now, I'll probably just use a full pc, but that still won't have video in.
*Which reminds me of a request I probably posted here before:
Expansion Capability. Give us some kind of expansion slot. Maybe a full SD card slot open to the top (like palm treo). We can use it to add whatever we need. All I can think of as existing now is wifi SD cards, and GPS. But it could be my above mentioned Video out, an IR LED (to use as a remote), radio tuner, maybe a camera. Other industry specific thing like walkie-talkie chip, multimeter, device net node, PLC, maybe a barcode scanner (laser emitter for use with the camera).

I'm with johnkzin on this one, the N800 was a bit big, N810 is just right for me.

Granted that is a lot of stored and transmitted data, not to mention the CPU needed to parse and display it all. However, in time those concerns will be meaningless.
