1) I don't mind that they abandoned full size SD. I mind that they went to miniSD instead of microSD. It doesn't make any sense to me :-}

Luckily, I have only so far bought 2 SD cards ... so I'll buying a micro-to-mini adaptor, and buying all micro cards from now on.

2) SIM/GSM/WiMAX ... based on some things TexRat hinted at, I'm guessing that we'll end up with 4 devices on the market:
a) N800 - no keyboard, no WAN, no GPS
b) N810 - keyboard, no WAN, GPS
c) N820 - ?keyboard, WiMAX, ?GPS
d) N830 - ?keyboard, 3G/4G GSM, ?GPS

I hope the N820 and N830 have keyboards (with a better layout), and I don't care one way or the other about GPS.
