Scoot over to the iTunes Store and you'll find a free Single of the Week and now a free App of the Week (currently a $US0.99 game called 'Cut The Rope').

But there's nothing similar at the Mac App Store. All Apple's offering to Mac owners is a pointer to 'Editor's Choice' apps at their usual prices (which, it must be said, is free in some cases).

The thing about app stores is that if you don't visit, you don't spend. The knowledge that there's going to be a new, free item every week is a fairly strong incentive to stop by regularly. As it is, about the only time I visit is when the badge on the App Store's Dock icon tells me there are multiple updates waiting to be downloaded.

And talking of neglect, the 'We Want a New Macpro' [sic] Facebook page is gaining attention. As of this writing it has over 14,500 Likes, and the count is still growing.

Started by Lou Borella earlier this month, it's essentially an online petition asking Apple to clarify its plans for the Mac Pro. Is a new model coming, is the Mac Pro about to follow the Xserve into oblivion, or is Apple going to license the OS to a manufacturer that can build powerful desktops?

I can see where Lou's coming from. Historically, new Mac Pro models appeared at 14 or 17 month intervals. It's now been almost 22 months since the last announcement if you exclude (as I would) the 'Server' configuration.

As powerful as today's iMacs are compared with their predecessors, some people need (in the sense of being able to cost-justify) the fastest processors, 64GB of RAM, scads of internal storage, and multiple - as in more than two - displays. It's not so much that the Mac Pro is more upgradable over time than the iMac, it's really a matter of being able to get the right configuration from the start.

If Apple's decided it doesn't want to be in that business any more, those customers will probably be saddened, but a clear announcement would let them move on. It seems that a fair proportion aren't prepared to wait much longer than WWDC for the announcement of new Mac Pros before starting to plan their migration to Windows.
