If you are looking for budget notebook, Acer will fit very well....they are good value for money laptops, with adequate performance and relaibility.....I have used one for the last 3 years, and have had minimum complaints...only, for last 5 months or so, the fan is a little noisy

High end laptops include HP and Toshiba....they are reliable, efficient and will serve your business needs as well....

The important thing to look for is the configuration. Nowadays, minimum available is Intel Core 2 duo processor 2.16 GHz, with 1 GB RAM and 160 GB HDD.
