[Thinkpad] NEED NEW COMPUTER FOR DAUGHTER

[The Floyds]

My daughter is headed off to college and needs a new computer.  She has a
thinkpad A20 and I am thinking of a T60 or T61 but don't have any experience
with buying a new one.  Any suggestions on what to get her?  She is not a
gamer and NU suggests  at minimum a 1.83 Ghz core 2 duo processor with win
XP pro or vista business, 128 MB video, 60 G hard drive, DVD+/- RW,  2 GB
ram, 10/100 ethernet, 802.11b/g wireless, minimum 2 USB ports, 3 yrs onsite
next business day and complete damage recovery.  I don't know what complete
damage recovery refers to either.  They figure this system should last her 4
yrs but she plans on medical school so she will need one longer.  Any help
you experts out there can offer is much appreciated.
