Definately my computer with satelite connection.....I could design lots of things then.
I guess a generator to power it would be the other thing but apart from that ummmmmm scissors I think!!
If I was taken to a desert island I'd be hopeing to have some tools with a dual purpose - perhaps a really good craft knife with lots of spare blades in the handle - could be used for cutting out crafting things and for cutting other things around the camp. My second tool would be something multi-purpose as well, perhaps a Helix craft room tool with all the bits that were included with it when I bought it. Is it cheating to take a multi-purpose tool? Now all I've got to do is learn how to make paper from whatever is around!
I'd have to have the same as Vicki, I cannot be parted from my laptop for more than five minutes and if the internet goes down, I'm totally lost. Just the laptop and internet and of course power and I'd be happy forever.
