to come from Linux to FreeBSD

[Mihamina Rakotomandimby]

Hi all,

I am from Linux (Debian & Ubuntu) and I will have to intensively use 
FreeBSD on servers (DNS, Database, Routing...)

I would like to install a FreeBSD on my laptop (Dell Inspiron, or some 
Asus not defined yet) and then virtualize a lot (KVM seems OK) in order 
to get used.

For the install on a laptop:
If my Wifi chipset is ever unsupported is it probably the same status if 
I try to switch to a FreeBSD derivative?

Or more precisely: What FreeBSD derivative would you recommend if 
wanting to have a usable laptop that can virtualize several flavors of 
FreeBSD derivatives?

Thank you all.
