Which Linux Distro?

[AZ_Pete]

Hello All,

I need recommendations on which Linux Distro to use.
I convinced my brother to try Linux and I have one shot to convert him from
the dark side ;)
He is well versed with all flavors of Windows and quite compentent around
computers (building, configuring, installing, etc).
He has never used Linux, but is interested in trying it.  I've been using
Redhat, TurboLinux, as well as Solaris.
While these OSes are user friendly to me, I feel they may be a bit complex
for a Linux newbie to install and would scare them away from Linux.
What would you guys recommend for a Linux Distro that is easy to install and
uses KDE or GNOME by default, and has a good variety of apps (email,
browser, Word Proc, spreadsheet, etc).  Ease of Installation and Ease of Use
are most important, since I will only be able to provide phone support (he
lives in IN and I live in AZ).
He has several computers which he can use so hardware shouldn't be an issue.
Basically, hardware is standard x86 stuff - P2 or P3, 128Mb Ram, PCI or AGP
video, IDE hard disks, IDE CD-ROM.

Any thoughts would be appreciated.
Peter
