I would say in the non enterprise...
...side most of us that want SSDs have now got them where we need them. Not to mention the old SATA side ain't cutting it anymore and that's not going to help a lot of us till next upgrade time.
Now it's down to encouraging all the folks who are unaware their 5400rpm HDD in the laptop is holding them back.That's the mums and dads.
Would also help if the OEMs started pushing SSD tech into laptops costing less than £750.
