Does anyone know when/if Orange will be making these available again?

Also, it's possible to buy one of these (and other phones)  for circa
£500 on-line from Expansys etc.  Under normal circumstance such phones
are available on contract for a fraction of the price - say £100 plus
£35 per month for 18 months.  - the contracts include texts and calls
etc.  Therefore why would anyone want to lay out £500?  Am I missing
the point?
