I second that opinion. If you manage to get one with a good screen
(1920x1200), with a T9600 processor and with a good quality SSD, this one is
a fairly modern laptop. Or maybe workstation, considering the weight.
If weight is a concern, the T400 is also a very good choice.
If you haven't tried one yet, I highly advise you buying an SSD - it totally
transforms the experience. Firefox opens in an instant. Compilers run like
crazy. The battery lasts longer. It's about 5 times more shock resilient than
an HDD.
