Im a linux:newbie.
I have seen linux in action, have always been curious about it. but really know little about it. im ready to take the dive

I got my hands on a compaq armada 1550DMT laptop which I upgraded to its
whopping 80mb ram. it has a 4 gig HD and 133mhz pentium processor.

I plan on just using it for the very basic stuff. word processing,
internet,email. MAYBE occasionally downloading something once in a while but
thats not on top of the list, so mostly just email and web surfing.

its currently running win me(yuck)
i have a generic wifi card that says its compatible with red hat.
(11MBPS wireless lan pcmcia adapter)
will red hat run on such a low laptop system if i install it? if not what linux
shoud I go with and what wifi card would be compatible? Does the linux os come
with a firewall and virus protection or would i have to use Macafee or norton or
something(and are these linux compatible as well)?

I appreciate any and all input.
