I'm having a difficult time with an appropriate response to your post, but I will respond in the best way I can without the Lol's.
Yes, large corporations validate their platforms. It's a functionality, compatibility testing. That does not mean I have engineers running around testing voltages in chips. It does mean that I have guys making sure all our apps / drivers / hardware runs without exception.
It's also why corporate platforms are stable. I know what equipment I'll be buying 1.5 years from now. I will have equipment in house 2-3 months before it is released to the public. I will know at least a year in advance when my vendor is making a platform change, and my vendor will query me on how many of the old systems I am going to want to procure after EOL. They will then pull that many off the line and warehouse them for me so I don't have to change platforms at a time that may not be opportune for me.
Everybody in the Fortune 500 does this.
As far as seeing 3 or 4 versions of the same laptop come out, are you saying you have 3 or 4 different OS images for the same laptop now? I'd shoot my supplier if they had me spending the time and money to maintain that for a single model. I'm back down to one laptop image, and by June I'll be back down a single desktop image again (we put off refreshing for two years when the economy blew up, so I was starting to get a wide variety of hardware, three models of laptops and two desktops.)
Edit:
Here's what Derek Meyer had to say about it in his last CC:
Code:
Well, I just think that it's a big market and with products
only in the market for roughly 90 days there's a seed program,
a certification cycle, before enterprise buyers really start to buy,
so this is not a consumer marketplace where boom, the product's
there and everybody turns on to it immediately.
