So Apple is now offering a 64GB Flash-based drive (aka SSD, or solid state drive) as an option on the MacBook Air.
But here's the thing: it's known (because people murmur it) that Flash has a limited life, because the number of times you can write to a block of storage is limited. At some point, the capacitance breaks down and it won't hold the charge any more. Bzzt, that bit of memory is gone.

And since you were wondering, the time before your 64GB SSD is hosed in the above implementation is 51 years.
If your SSD-equipped MacBook Air is still in use 12 or especially 51 years from now, then you might need to be able to replace the drive. But by then it'll probably be wired into our brains...
