(K)Ubuntu & Mac OS/X

[Alain Muls]

Hi

I am looking for a replacement of my portable.

I am very much tempted by the new Mac OS/X and its intel based Mac's. Is it 
possible to
1. create a dual boot between OS/X and (k)ubuntu?
2. is it possible to use the existing OS/X installation and run with Xen or 
VmWare from (k)ubuntu 
3. is it possible to run the (k)ubuntu from the OS/X boot using parallels(?)

Tx/ALain
