I saw question about n97 mini concerning C. DRIVE, not sure if it was answered but the C drive on mini is over 300mb, they gave it twice the amount of NAND memory(512mb on mini) compared to n97 to help performance. still only as 128mb of dedicated ram though
i think nokia learnt from the mistakes of with n97,
N97 will get awesome firmware 2.0 update october which will boost performance and add new features
