It should be SOP to image off what is on a machine, format [1] it and reload from media

It doesn't help that at various times MS and their OEMS have made this a PITA with many machines not shipping with "clean" windows media, some keys only working with some media, keys printed on the machine that required a phonecall to activate and so-on. At one point they were even threatening companies who used their vlk media/keys to reimage machines running under OEM licenses though they later backed down on that and introduced "reimage rights".

A comparision of a first generation desktop i3 (which is slightly newer than a first generation i7) from january 2010 to a current generation desktop i3 from may 2014 (there was a slight speed bump released in july but anandtech don't have that one in their list) can be seen at . We see that performance has less than doubled in over four years

We see a similar comparison when we compare a first generation desktop i5 from september 2009 to a current one from may 2014

I'm not sure i'd consider it insane for a high end desktop part to have double the performance of a contemporary desktop part. I think it's more that we just aren't making the massive jumps in performance anymore that came from the move from 1->2->4 cores as the typical core count in the mid-mainstream or that came from retiring the crappy pentium 4 architecture.

Even within one generation the good/better/best breaks down once you start looking across product categories, an "ultra mobile" i7 can be considerablly less capable than a "mobile" i3.

Like most stuff marketers come up with it's pretty clearly designed to mislead customers into thinking they can have both an ultra slim lightweight machine and top-tier performance.

linux seems to average a release about every 2 months. Which would mean a series every 40 months. To fill up series 4 through 19 inclusive would take about 16*40=640 months = ~ 53 years. According to google linus is currently 45 so that would make him 98.

I would expect him to be at the very least retired and quite possiblly dead by then.

no one ever lost money faithfully following that advice

Becuase faithfully following it is not possible.

You don't know what will go up in price, you can only make more or less educated guesses. If those guesses are right you make money, if your guesses are wrong you lose money.

You took a rather roundabout route to a somewhat inaccurate value of what 40dB meant.

The definition is that +10dB is 10 times the power. So +40dB is by definition 10000 times the power. 3dB is only approximately a doubling.

But that doesn't explain the figure you gave. A "third of a doubling" would mean multiplying by the cube root of 2 which would give an answer of about 10321, still somewhat off from the correct answer but substantially closer than the figure you gave.

and will answer a lot of performance and memory issues at least compared to the Raspberry Pi B+ or the Beaglebone Black.

but comparing it to those isn't really fair. Assuming it will be somewhere between $100-$200 that would put it in the same price bracket as the higher end options from the likes of wandboard, solidrun and odriod or even the atom based minnowboard.

And viewed in amongst that pack it doesn't seem especially exciting. I guess if you really must have both A15 cores (but only 2 of them) and native SATA then it may be a good option

The biggest problem with the Pi in my eyes is that (for some BS reasons that don't seem entirely clear to me) it still needs a closed source bootloader on the VideoCore side of things in order to actually use the thing.

The "videocore" is a bunch of modules including a processor (the "VPU"), a 3D core, various video related stuff etc. The SoC is booted by the VPU, the arm is inactive until the VPU starts it.

specs for the 3D core were released but specs for the rest of the videocore including the VPU remain closed :(. There have been some attempts at reverse engineering but with limited success.
