Any MAEMO (N900) users there that can capture some data?

Any N900 (maemo) users out there interested in helping out with a quick experiment?
An enterprising developer has published a LUX reporting tool for the N900 here -> http://www.tuug.fi/~toni/serendipity/in ... -N900.html
Having issues with the brightness of my Lenovo W500 Samsung display I thought I'd try measuring the L/R/Top with this tool -- just for a more objective, albeit uncalibrated view on brightness.
In each case I placed the proximity sensor directly over the panel, so it was around 5cm "in" from the edge
Here's my rough results
Lenovo W500 (full) R=083 L=063 T=060
Dell 2005fp desktop (normal) R=151 L=155 T=142
old? HP 17" 4:3 (normal) R=157 L=143 T=180
Dell Studio 15 1920 laptop led (in dark room) R=104 L=111 T=110
Dell Studio 15 1920 laptop led (full) R=214 L=212 T=226
Dell Studio 17 laptop led (full) R=300 L=314 T=297
? HP 19" unknown (low lighting) L=098 R=107 T=113
? HP 19" unknown (full) L=138 R=153 T=162
The W500 is on full brightness & using the appropriate monitor.inf under win 7
What I should really do is have a proper colorimiter calibration and measurement done.
The "spec" of the W500 panel is 180-200 I believe - it's clearly not fair to use the numbers literally, but something is very wrong.
Anyone else fancy measuring a "current" laptop for comparison -- especially any other W500 owners (some of which have samsung panels, some have LG panels)
Posting in the general forum as it would be interesting to get a feel for what's "normal" in the line, beyond that whether my W500 is normal -- as possible prep for taking up the issue with Lenovo etc.
