differences between T30 and T40 IBMs?

[[A]varice]

im thinking about picking up a T40 or T30 off ebay.. whats the difference between the T40 and T30? they seem very similar to me... but the T30 is a couple hundred cheaper.. someone please enlighten me!

t40 = smaller, lighter, and more powerful.

the t40's will also have better battery life. if you wanted to, you could upgrade the battery to the new higher capacity batteries ibm is offering.

T30 uses a Pentium 4-m
T4x uses a Pentium M

beyond that, the T4x is thinner & lighter. Never used a T30...so I dunno.
