- I've heard that there's a difference in Airport Base Stations (ie. Rev 1.0 versus Rev 1.1 versus Rev 2.0). What does this mean exactly? Does this mean that certain updates from Apple that take advantage of Rev 2.0 are not compatible to Rev 1.1 base stations? I realize that Rev. 2.0 base stations have better security encryption and two Ethernet ports. Is there any reason not to buy the Rev. 1.1 base station at a discounted rate to gain Airport functionality?

- Is there a significant difference in Airport cards? Meaning are there different versions of the Airport card that are incompatible with the different base stations? Or buying one Airport Card gives you compatibility with all updates? I've seen some airport cards on the cheap ($49), and was just wandering if they are obsolete.

- What do you guys (gals) think will be happening with the supposed updates coming from Apple with improved Airport (IEEE 802.11g) functionality? Does this mean new airport cards and base stations? Or would it be a firmware upgrade?

- Does anyone know what's entailed with installing an airport card inside a G3 iMac (350 MHz)? I remember mention awhile back that a bracket had to be also purchased to mount an airport card inside the iMac. When I opened my iMac I saw a connector to attach the card, but have no clue other than that fact.

Thanks for your input.
