People have been saying things just like that for years now.
"once apple does this"
"once apple does that"
"once (x thing) is complete"
"once next year comes around"
"once the new OS is mature"
"once apple kills the market for clone macs"
Etc etc etc................
Having worked in an Apple store I can attest that because Intel always had different chips it was real hard to convince a potential customer of a comparison.
Now they have machines using the same chips, which can run windows if they need to. With no performance hit. Demonstrable in store.
The reason for slow sales now is the transition between the two platforms.
