This. The desktop PC CPU spec wars were over about 5+ years ago. With the benefit of hindsight, it seemed to hit this point with the release of the Intel Wolfdale Core2 Duo / AMD K10 Deneb cpus.
After that, there seemed to be little new CPU technology that made desktop computers "seem faster" in great multiple leaps, except for hard-core gamers and other edge cases. However, having 2 or more gig (ideally 4+ gig) of ram seems to be important. For example, I got an Intel E8500 Core2 Duo (what's that... circa 2009?) and maxed it out to 8 gig of ram (motherboard/slot limit).... the thing hardly breaks out in a sweat in Windows 8.1. I don't think I could tell the difference between it and some new i7 thing if they were sitting next to each other doing the same (non-gaming) tasks.
Naturally hard-core gamers want more CPU power, but a lot of the needed grunt comes from the newer and greatest GPUs. For those in an office and/or just internet surfing, anything beyond a RAM-maxed Wolfdale/Deneb is just overkill - reflected in Microsoft's almost static system requirements for Windows Vista, 7, 8, 8.1 and beyond.
How about a Macintosh SE/30 and Cyberdog?
I'm only half serious.
Ironically, they are actually doing something similar to this in some Asian countries (well, minus the "copter" part), as "McDelivery".
They trialled this in Australia a while ago and people carried on like it was going to end western civilisation - oh, wait...
Yes, just like that.
Wait—were you making a joke?
Never ask two questions in a business letter. The reply will discuss the one you are least interested, and say nothing about the other.
