Help please!

After studying my 505, my wife has been hinting for ages she would like one of these new fandangled readers.
So I've been waiting for Sony to get the new ones out, and true to form three come along at once, so now I'm stuck.
The two candiates are the new 650 & the 350...
I am more than willing to pay the £200 for the new prs650 with the 6" screen, but it only comes in black or silver.
So - go for the lovely pink one with a 5" display which is lsightly more portable and I'll spend the £50 saving on something else for her, or the boring coloured 650 with the 6" display. The other differences in the two models do not matter.
Please help!
