Apple Airport Express 'g' versus 'n'

[Tonys]

Hi quick question about this.

I have a Airport extreme that connects my external hard drives to my macbook.
Now im looking at getting an Airport express for airtunes. Do i need the 'n'? or will 'g' be good enough.
My network at the moment is 'n' via the Airport extreme.

Thanks in advance

I have the G and its fine.

Be aware that if you have the single radio version of the Extreme you cant use 802.11n if there is a "g" device within the network.

So for instance:

Macbook
Airport Express N
Airport Extreme N

= N speeds

Macbook
Airport Express G
Airport Extreme N

= G speeds

Cheers for that.
How do i tell if i have the single radio version?
Whats the other version? Can i still have n speeds on the other version?

The other version came out last week.

That answers that then, cheers.

Dont really want to drag it down to 'G' so ill need a 'N' express.
