Forums: How many cores, Apple retail

Forums roundup: Members are taking part in a poll asking how many cores is enough for them, with the options of two, four, and eight cores.... Other users are discussing the incentives offered by various Mac retailers, leading to some users question if there is any reason to bother buying direct from Apple.... One user is wondering whether or not they can interchange MacBook and MacBook Pro power adapters at an office using both laptops.... Other members are offering advice to a fellow poster who has noticed odd 'streaks' on their iMac screen.... Meanwhile, other members are trying to help solve some weird behaviour from a second monitor attached to a PowerBook.
