Hi, I am planning to buy an iMac and like the idea of ordering it with the wireless Mighty Mouse and wireless Keyboard. Is this a reliable and hazzlefree solution? I mean, what are comments from people using the wireless Mighty Mouse and wireless Keyboard? Also, is the changing/recharging of the batteries a big downside? I plan to get rechargable batteries. FYI: the iMac would be my home computer, so I'd mainly use it in the evening and on the weekend. Thanks!
