a/b/g vs b/g for laptop network adapter

[paleo]

forgive my computer ignorance, but what advantage would 'a' networking have over an adapter without it?

'a' is rarely used, just get the b/g one.

Typically most a/b/g adapters cost more than your regular g adapter (which is backwards compatible with b)

It'll probably be cheaper to go with g/b... and since like B0000rt says, a is rarely used anymore, so you're not really losing out on functionality (unless you have a big 802.11a setup already, I suppose)

Don't forget about b/g/n :).

You mean b/g/pre-n
