As I said here and in another thread, I use .11a at home. Why? Because in my apartment building and probably the other buildings near me, there are more than 7 access points running. .11b/g simply won't work very well in such an environment. It's how CSMA/CA works. Add on 2.4GHz cordless phones and performance just sucks. So I swapped my 11g AP for an 11a AP and viola! Instant high speed performance. Once the rest of the market understands this, a whole lot more people will switch.
