In regards to the MicroSD, look at the N900. Having a separate file system on micro sd has really helped the development of things like MeeGo and Android on the device, if nothing other than from a testing standpoint. I wouldn't reflash my brand new N9 with Android, but if I could boot it off of an SD card I'd be all for it. Also, price. Buying a straight up 64GB phone, is going to cost a lot. Why not get 32 and expand later when you have extra money, or when prices of SD cards drop?
