And, yes, I realize you could also “Cast” to “DateTime” first (and if necessary back again to “DateTime2”), but you’d lose the extra precision and again, the extra range (all prior to year 1753) benefits of “DateTime2” vs. “DateTime” which again are probably the 2 biggest and also at the same time, probably not likely needed, which begs the question why use it when you lose the implicit / easy conversions to floating-point numeric (# of days) for addition / subtraction / “age” (vs. DateDiff) / Avg calcs benefit which is a big one in my experience.
Recall that in a single processor system, parallel execution is an illusion. One instruction from one process at a time can be executed by the CPU even though multiple processes reside in main memory. Imagine a restaurant with only one waiter and few customers. There is no way for the waiter to serve more than one customer at a time but if it happens that the waiter is fast enough to rotate on the tables and provide food quickly then you get the feeling that all customers are being served at the same time. This is the example of time sharing when CPU time (or waiter time) is being shared between processes (customers). Multi programming and multitasking operating systems are nothing but time sharing systems. In multi programming though the CPU is shared between programs it is not the perfect example on CPU time sharing because one program keeps running until it blocks however in a multitasking (modern operating system) time sharing is best manifested because each running process takes only a fair amount of the CPU time called quantum time. Even in a multiprocessing system when we have more than one processor still each processor time is shared between running processes. As you can see all terms are somehow related in one way or another however not using the right term in the right context is what makes the confusion so keep that in mind.
• Road warriors: People who shove their laptops into their bags indiscriminately will want the extra security of an SSD. That laptop may not be fully asleep when you violently shut it to catch your next flight. This also includes folks who work in the field, like utility workers and university researchers.
• Speed demons: If you need things done now, spend the extra bucks for quick boot-ups and app launches. Supplement with a storage SSD or hard drive if you need extra space (see below).
• Graphic arts and engineering professionals: Yes, we know we said they need hard drives, but the speed of an SSD may make the difference between completing two proposals for your client and completing five. These users are prime candidates for dual-drive systems (more on that below).
• Audio engineers and musicians: If you're recording music, you don't want the scratchy sound from a hard drive intruding. Go for quieter SSDs.
