Is there a first and 2nd generation Time Capsule?

[SPNarwhal]

And if so, which one is the 1tb model number MB765LL/A ?

And also, what is the difference between the first and 2nd gen?

How much do these usually cost?

I write this from memory based on some announcement I read. I think the 2nd gen time capsule can do dual band wifi networking and has a large reach.

But, as I said, from memory.

so there's 4 generations.
and this one is a 2nd gen.

would it be worth it to buy the 2nd gen 1tb for 175 dollars? (brand new, sealed)?

how much difference is there between the 2nd from the 3rd and fourth?
i mean, what differences are there really?

i mostly just want to use this as a wireless backup, i don't care tooooo much about the wireless router/modem thing.
but to store my files and access them wirelessly would be pretty nice.

does anybody know the differences between the 2nd -3rd/4th gen?
and is 175 a good price for it?
