There are lots of other funtions and specifecations to consider when choosing computers for your office. Here's a few other things to think about before getting out your credit card:

Disks  

These are used to store your files, images and data. The bigger the disk drive, the more you can store on your PC.  Most PCs come with very large disks that have for more capacity that you would need in normal business use. Look for about 80Gb in a desktop PC and 60Gb in a laptop.

Removable media

Your base requirement should be for a CD/DVD ROM drive – i.e. a drive that can read CD ROMS and DVDs. This drive will allow you to install software onto the PC. If you have a centralised server to back up your data, it is essential that the drive will also be able to write CDs and DVDs. If you cannot write to CD it is important you have some other solution to back up your data.

Note that some laptops:

Sound card

This is usually built into the PC. Sound is becoming an important part of many business programs and you will need a speaker and microphone if you intend to make calls over the Internet.

Modem

You might need this to connect to the Internet if Broadband is unavailable in your area or if you cannot afford it. It is also a useful fall back if your broadband connection goes down for any reason. 

Network card

You might need this to c onnect to an office network, connect to broadband or for ad hoc connections to other PCs.
