Er... that's not the point he's making. If you don't want to buy a phone that you have to wait 6 months to get an update, you must get a Nexus. Any iPhone you buy today that's fully supported will get an update the same day as Apple's latest phone.
So why was he talking about the restriction on the number of devices(Nexus) one can choose from on Android if you want the latest updates like its a negative thing or something?
It's obviously not a negative for iOS because you have an artificial restriction on the number of devices you can choose from there as well.
If choosing 1 from 3 out of 3 iOS devices is not considered a restriction, I fail to see how choosing 1 from 2 different Nexuses out of 100+ Android devices is a restriction.
If I go to a car dealer(Apple Automobiles) and I tell them I want silver(or in this case, "the latest OS updates") and they only have 3 cars on the lot but they're all silver versus another car dealer(Android Automobiles) that has 100 cars with only 2 silver ones, is that really any different?
You're still getting the silver color that you wanted(or in this case, the latest Android updates) rather than waiting 6 months or a year for the car dealer to order your color(or in this case, waiting 6-12 months for the manufacturer and carriers to deliver the update).
Google has also announced a change in it's Nexus policy. You don't get to chose between only 2(Nexus S and Galaxy Nexus) Nexus models any longer. You will soon now get to choose one from each manufacturer.
Again choosing between 3 out of 3 iOS phones and choosing between 2 out 100 or 5+(Samsung, LG, HTC, Moto, and Sony would all have their own Nexus lines yearly if Google's new idea pans out) out of 100 Android devices to get the latest updates isn't any different. You still have only 2 or 3 devices to pick from.
Either way there is still an artificial restriction between both OSes. It's either a valid criticism for both iOS and Android, or it isn't for either one of them.
There may be more junk on Android for those that want the junk, but one can't invalidate the fact that the same exact opportunity is still there to get the latest updates.
Now if you're talking about going to a casino blindfolded and selecting 3 out of 3 vs. selecting 2 out of 100, the odds are completely different but no one on this forum goes in blindfolded, right? Everyone here knows what a Nexus is, so this isn't news.
