Yeah Ronni, Another neat little trick!
Interestingly with my two iMacs sat about 1.5m apart in the same room, the plastic-backed older 24² iMac consistently shows a transmit rate of 54 (ie the max for my ³g² level Airport Express) whereas the new metal-backed 27² iMac shows a lower transmission rate (has varied between 36 & 48 on a few recent checks). The RSSI (received signal strength indication, Reg) shows differently on every check - changing from around 68 to 76 so far but, interestingly, the RSSI for the new iMac is sometimes better, sometimes worse, than the old iMac but the transmission rate is always lower. At first, I thought the slower transmission rate of the new iMac was probably down to the metal back cutting down the reception relative to the old plastic back however, if that was the case I would have also expected to see the RSSI as consistently lower? For what its worth, the new iMac is running 10.6.2 while the old iMac is running 10.5.8 and I note that there is more info shown under 10.6.2 than 10.5.8, eg: Phy mode: 802.11g and the freq. (2.4GHz) after the Channel number also 10.6.2 shows Airport scanning for new networks around every 10 seconds, whereas 10.5.8 doesn¹t I¹m presuming it is still scanning for new networks, but just doesn¹t display this info under 10.5.8?
