New computers for the office - Suggestions???

+1 on Lenovo. Had a T60, then T410 and about to buy a T530. They have a 10% sale here on in the UK not sure about US.

Shame they changed the keyboard to chiclet style but overall I have few complains with these machines.
 


When I bought my thinkpad, I got a decent deal using lenovo's shareholder purchase program. Kicker was, I wasn't a shareholder. =)

They usually have decent deals in their outlet as well.
 
One of the Lenovo ThinkPad T-Series sounds good for your needs. Excellent battery life, fast, and designed for business (I've dropped my ThinkPad from a roof and it still works). The starting price is $701.
