I still love my Voyage, so much so that I have purchased a brand new 'Citron' cover for it instead of buying the Oasis!
If it ain't broke don't fix it.
And as the Oasis doesn't offer anything drastically different (apart from a clunky shape and some sticky-out buttons), I decided to get my Voyage a present so I won't be tempted to make a pointless and expensive 'upgrade.' Some upgrade.
