The N9 and (especially) N950 look delicious as hell. My only problem is that I use my N900 for:

-Easy Debian
---MitM attacks
---Web server
-Packet Injection
-Game emulators [GBA, NES]

And I love having full Debian [EasyDebian] and Debian-based [Maemo 5] installations, using apt-get, rooting, etc.

So my questions are:

1) Is MeeGo as "hackable" and open?
2) Can I obtain root?
3) Will we be able to do packet injection on the N9/N950 hardware?
4) Will we have access to the thousands of Linux/Maemo apps like on the N900?

I especially look forward to having a device with NFC hardware I can mess around with. ^_^
