Alright guys, I'm now thinking of getting this Android on my N900 as well as I can't wait anymore :P .. Anyways, I had a couple of questions:

1) Firstly a general question: Is installing Android onto N900 at this stage (e.g. cannot make phone calls, slow OS due to software emulation for graphics, etc ..) worth it ? ... Remember, this is a general question, and I know of all the risks, etc .. so assume there are no risks ... Should I go for it now or is it better to wait some more ..

2) Suppose I install android now, can it be totally uninstalled easily at a later time ... ? (like remove the bootloader, and the Android partitions, etc ..)

3) Also, suppose I install Android and then there's a fix out on how to get the phone calling thing working for example .. Can I just apply the update onto my existing Android install, or do I reinstall everything from scratch with the new update .. ?

4) Which version of Android is available as of now, 2.1 or 2.2 ?

5) Would I have access to the Official Android Market and be able to install apps from there ?

6) Which of these guide to install Android is the most up-to-date ? (I can't tell :P): this, this or this .. ?

Thanks in advance
