It’s fairly simple to run a hard disk and an SSD simultaneously if you have the right notebook model. For everybody else – and that includes us –, it’s still quite possible even if it takes time. A notebook designed with flexibility in mind, that uses removable peripherals (like the Dell pro models, Lenovo, Toshiba, etc.), is obviously better suited than consumer-grade machines (or in our case, a Mac).
As for the SSD itself, its performance is impressive and it’s truly a joy to use. But is the user comfort worth the high price of an SSD? That’s up to you to decide. If you have the cash available, the answer is clearly yes. But if the price aspect is a problem, we strongly advise you to wait. SSDs are a recent solution (as far as the general public is concerned) and they’re constantly evolving. So expect prices to drop regularly.
