I'd like to see how the MacBook and 13.3" MacBook Pro sales fair after this release. Apple's platform is too flat with barely any differentiation beyond this model was just updated vs. a slightly older one.
It is going to take a while for the real relative wieghting that the market puts on these to stabilize.
After the MBA first appeared in the line up it shot to the top of the "top 10" on the Apple store only to fade over time ( especially after the MBP 13" showed up). I won't read too deeply into the rankings for first month or so.
Right now a couple of Apple retailers are running specials on the entry level MBP 13" that pushes it into the $999 range. At that price it is holding its own ( on Amazon right now still out of in front of the MBA ). I think the MacBook is getting clobbered though. At $899 (and lower at discount retailers) it probably would hold up better.
I doubt these MBP 13" specials will last an extended period. I think retailers are just trying to dump the entry level models as fast as they can because of the they loss a bit of an edge because now metal cased Mac that is cheaper. Price is one of the dominant factor for most folks.
One of the major problems is not that the Mac laptop platform is too flat but that a $999 floor is put on the pricing. What you have is a logjam at that price point.
I suspect that in the Spring the MBP 13" will get a discrete GPU, a Core i mobile processor, loose the DVD (maybe get two drives and tack on another $100 ), and jump in price by $100 (due to GPU).
That would straighten out the pricing so that, when looking at entry level models, it went :
MBA 11" $999
MBA 13" $1299
MBP 13" $1399
MBP 15" $1799
MBP 17" $2299
With a Core i , SSD + HDD , and discrete GPU the MBP 13' would smoke the MBA 13" in all kinds of ways when it comes to performance and value. Enough that a decent number of people who need performance and storage will stretch the extra $100 in decent numbers.
Apple could do a crippled MBP 13" (no DVD , 2GB RAM , no SSD ) if wanted to squeeze into the same $1199 spot in now. Basically would take out components so that extra $100 for discrete GPU and VRAM was tradeded off. Then have "better" and "Best" models to bring it back up to competing better than MBA 13". The entry model would be on that folks on budget bought and then upgraded with 3rd party RAM, drives , etc.
Seriously annoying that FW would jump to a $1399 entry point, but that is the kind annoying move have come to expect Apple to make. Perhaps though the could take the crippled MBP 13" above , remove the keyboard backlight, use low res screen, and just name that MacBook. They'd be able to slot that in at $1099 probably. If they did that then probably don't need the "stripped MBP 13". So
MBA 11" $999 [ weight and size matter most. ]
Macbook 13" $1099 [ need value and flexibility, but metal case. ]
MBA 13" $1299 [ size matters slightly less and text too small on 11" ]
MBP 13" $1399 [ need above average performance in small/light enough package. ]
MBP 15" $1799 [ need above average performance, portable, and larger screen ]
MBP 17" $2299 [ need way above average performance, large screen (1080p without having to squint at details in the frame and some controls still left on screen) , luggable, and connectivity: DVD and ExpressCard ]
That would put them back into differentiated models. For example, all MBP's have discrete GPUs (with optional low power integrated mode). Ditto for MB. All MBA have integrated graphics.
All those changes keep the $499-899 range open for iPads. Apple can probably get another year or two out of pretending that quality laptops can't be priced in this range.
Not sure what Apple does next year though. C2D again for MBA would be a stretch although there should be better integrated graphics only options by next Fall. However, there should also be better single chip solutions with integrated GPU by next Fall too. AMD should have something that Apple can use at that point.
