Sell your G1, use the money towards the N1... Do it soon, buying the N1 via google won't last much longer, once retailers get ahold of it it'll cost considerably more.
The rumor/heresay is that the N2 will be out in Nov. Then just repeat the cycle of selling old, use money towards the new one.
Kind of like you're leasing the best phone at the moment
