It makes perfect sense, if one is considering fully switching to SSD's, to invest in their long term reliability.
EDIT:
Here's a quote from Anobit's technology page:
Specifically, MSP™ enables SLC (one bit-per-cell) endurance and performance with MLC (two bits-per-cell) NAND, and MLC endurance and performance with TLC (three bits-per-cell) NAND, resulting in a significant reduction in cost per-bit.
For those of you who haven't done their homework about SSD's, SLC's are really nice and reliable, but lack storage space, as they only store one bit per cell. MLC's and TLC's store 2x or 3x more (respectively) but they are less reliable and much more short lived. However, if their MSP technology really works (it does because otherwise apple would not be trying to acquire them) then you get the PERFORMANCE and RELIABILITY of an SLC and still keep the 3 bits per cell (or 3x the storage).
Effectively, this means cheap and high performance flash storage for Apple. And it makes perfect sense to buy the company and keep SSD's out of reach for everyone else.
