They'll just do what Apple did, like Windows 10.4 Tiger, Windows 10.5 Leopard, Windows 10.6 Snow Leopard, etc.
That might have happened during the bald Steve's reign, but Nadella is actually making decisions that make sense. Instead of being a high profile in your face guy, he's listening to customers. The Windows 10 Preview project is very well thought out, so far
In the 80s and 90s. X terminals and the like. Sooner or later the users want their power back. It will be interesting to see what happend this time around.
Not apples to apples. X terminals were typically terminals w/o CPU, memory, storage or anything - everything had to be done remotely on a server, and access to those things over a network, at the time, was slow. Workstations were fast, but an X terminal connected to a server over ethernet was pretty slow due to all that latency.
In the case of tablets, it's not the same. Yeah, there is backup on servers (viz cloud), but it's not essential: one can have one's needed apps and data on one's own tablet. The CPUs are powerful enough to support pretty compute intense applications, while both memory and storage is cheap, unlike in the X terminals, that didn't have any. The cloud is just there as backup in case something crashes, or a tablet gets lost or stolen or broken, and a replacement needs to be quickly configured to the last working state. That's all it is.
VLIW/EPIC? The Russians should just buy up the Itanium from Intel, in return from a deal by Intel to build a fab in Russia where these could be fabbed. Would be a win-win for both.
But then the story headline is wrong - this is not a PC chip: it's a server, or at minimum, a UnixStation chip
Always look over your shoulder because everyone is watching and plotting against you.
