Why is it stupid, most modern smartphones dont have ir ports atall, and the reason is because even when ir ports supporting IrDA were included on practically all phones, bugger all anyone used them.
What's the point in nokia spending time/effort/money developing support for a slow, crummy old file transfer method that isn't included on most other modern phones either?

Someone has mentioned before that at 30fps there is no way the camera can read the data fast enough for such purposes.
Lets put it this way, 30fps = about 30Hz, 1Hz = 1 cycle per second so 30 frames would be thirty cycles per second.
Standard consumer IR devices however have modulation speeds of 35-38kilohertz, or about what, a thousand times faster than the camera is capable of seeing.
I just checked one of my remotes: The shortest "carrier on" times were about 180 µs, followed by "carrier off" time of 900 µs. No, I don't think you could capture these accurately using a camera. (Interesting idea, though.)

when i say to my plumber i want a second sink in my bathroom...
then he installs a sink.... but when i try to wash my hands and there is no water... and i call him and ask him why there is no water... what would he say??
an ordinary plumber would say he comes the next day and will check what is wrong...
and a nokia plumber would say "that sink does not support water"
for what is the ir port good when it is not working??
just for the devs??
what will be the next step? a phone/tablet with gsm chip but no ability to call someone?? like when you can code a phone app you can call someone??
or a phone/tablet without os??
customer: hy i just bought my nokia N12000 an it showes me only a nokia logo and then it turns off...
nsc: have you already coded an os and flashed it into the device??
i love nokia... but why they dont finish their work??
half work is always crappy.... and like you sayed .... its an old technologie.... it wouldnt be such a problem to add the input ability...

Just putting the hole in the chassis must be more expensive than putting a proper IR receiver in there. I too have to wonder what was the idea behind this....

The IR emitter is to allow the N900 to control legacy items, not to provide a seriously outdated protocol
