Well, we just hired 2 new staffs and there's no extra PCs, so, need to buy new ones. Nowadays, for new PC, if you want Windows XP you need to buy Windows 7 Pro and then buy the downgrade to XP option. More expensive than just having Windows 7.
Most of the info is for Windows 7 Home Premium and Windows 7 Professional.
I know Windows 7 Home Basic cannot join a domain (can only use peer to peer) and some of it's transparent display doesn't work or something.
I think it should be ok using Home in office. It's the Dell agent to quoted us. So, she should know.
Well, you can complain that the computer is very slow, that it slow down your work. Maybe they will upgrade then.
Anyway, I prefer XP. But, they are slowly phasing out XP. So, it is better to buy Windows 7.
