Sub-notebook / Laptop

[xyz]

Hi,

Can anyone recommend a good sub-notebook (or similar) that satisfy the following conditions?

As light as possible
As small as possible
Capable of running full Windows 98/NT
Built-in modem
Good screen (colour)

Also desirable characteristics:
Long battery life
Inexpensive

Also, is Singapore still cheaper in terms of electronic gadget prices??

Thanks for your help!
