Since I posted the msg I spoke to dell they told me it starts a 4.0 lbs.
But otherwise it looks nice only big problem I have with it is the 4GB limitation, which is a problem for me. For a 2 GB notebook this is a great price.
That's probably with the adapter. If it's not up to your needs, I won't push it.
As far as the CPUs go, if all you are planning on doing is surfing the web, email and some MS Office type stuff then either the Asus or the Toshiba will be fine.
