I have an all Mac/Apple office except for a Dell laptop I bought for new employees to use for training. The Dell has been a disaster. Since day 1 it can barely go on the Internet. We have added zero software to it...we just need it to run internet based training modules. Anyway, I am going I replace it because it is costing me $$ because training is taking twice as long as it should! Would you just get a current MacBook Air? Or a previous generation? I likely have to purchase at Best Buy as they are taking back the Dell past the return window. Any brilliant deals out there somewhere else?
