The Mac Pro ships with enough bandwidth to drive three 4K desktop monitors, yet Apple's most recent monitor -- the 27" Thunderbolt Display -- dates to 2011 and has the same resolution as the current 15" Macbook Pro. Bluntly, this is disgraceful. Serious video folks are going to be buying Mac Pros and then paying ASUS three times as much for the monitors! Where's the Apple 4K Thunderbolt Display?
A keyboard cover -- like the Logitech Ultra-thin Keyboard Cover, or Microsoft's Surface keyboards -- would be nice. (I suppose Apple are relying on the after-market, as witness the startlingly fast announcements by Belkin et al.)
Finally, the "software is free" announcement ... yes, they're taking aim at Microsoft, but iWork 5 on OSX turns out to be a mixed blessing; there are regressions all over, especially in scripting (they've virtually dropped AppleScript from their office apps). What is this, an attempt to build market share for MS Office? (The mind boggles.) What other power user features have they planed away in the pursuit of a clean and consistent user interface across all platforms? (Which in practice seems to mean dumbing down the apps on the Pro platform -- OSX -- for compatibility with the mass market platform -- iOS.)
