Thanks for the heads-up on 802.11g. I would tend to go with whichever is cheaper. If I were to get 802.11a, I would keep my 802.11b access point running for backward compatibility. 802.11g would only benfit me by having one less geeky box. I actually prefer having as many geeky boxes as possible.

If I do go with a faster wireless, I have a bunch of devices that will still have to run on 802.11b. I cannot see any 802.11a-to-ethernet bridges on the market. 3 of the powerline bridges at $89 a piece (cheap) would cover almost every device in my apartment. The only one to remain wireless would be my laptop and 802.11b is fine for that.

The powerline suff keeps looking great because I have more devices with ethernet ports than cardbus or PCI slots. However, the chart below from this PC Magazine article is keeping me from taking the plunge.
