...On a desktop I don't think it would be to bad as long as the location of the machine was thought out and measures taken to control lighting. Heck blinds are cheap and might be all you need. I don't think the glossy is necessarily the deal breaker some make it out to be.
Exactly. I've got a 20inch iMac ordered. I know which room of my house it is going in. I control the environment. I will deal with any glares that may be there. Glossy screen is not a deal breaker.
