http://www.apple.com/wifi/This lists a summary of differences between the hardware. The wireless hardware on the latest airport express is on par with the extreme. The old version could do 2ghz or 5ghz, but the new one can do both. Not that it really matters. The reason to pick 5Ghz is more because there are less devices using that band, and the odds of interference are lower. The downside of 5Ghz is shorter range and less ability to penetrate objects, such as walls and bodies.In my tests, range of the two is nearly identical, although in some cases was marginally better with the Extreme. It was close enough that i would call it a tie.The Extreme has gigabit connections. For purposes of remote control of your board, it won't make a bit of difference. The small size of the express and the built in power supply makes it a great choice.If using the express with an iPad for wireless control, I've found that using WEP can cause latency issues that tend to piss off the app. Hiding the network, and enabling MAC address control works great.

That's very interesting Brian. I'm curious to hear more about your 'WEP-induced latency testing'.
I didn't take the time to do any numbers testing on the current hardware. ... This is why I came to the conclusion that the latency introduced by encryption is what was throwing off the apps. Most likely as the hardware was renegotiating the encryption phase, there was enough lag to throw it into a tizzy.
I haven't tried mac address filtering, but it sounds basically like it's stable, I wonder if it outperforms the dhcp server in terms of latency performance?
