This, more then anything is why this thread is so amusing. Consumer PCs/laptops now account for less then 20% of all CPU volume sales now, and that rate is in a rapid state of decline. With the exception of workstation/crunch racks which is already nV's cash cow, nVidia is in a very strong position moving forward. Simply take a look at all of the high end phones and tablets coming out in the first six months of 2K11.
nVidia is supposedly doomed because they are being pushed out of the lowest margin chip segment of the rapidly contracting PC segment of consumer electronics, despite currently being the 'holy grail' of the white hot and exploding ultra portable market(Toshiba, HTC, Samsung, Motorola, Dell, MSI, Notion, LG, Asus- are *ALL* using Tegra2 for their flagship ultraportable devices for announced 2K11 products). So nV gets pushed out of the lowest end portion of a ~300 million unit a year market and takes over the high end of a 1.2
billion unit a year market, and some how this spells doom. I don't see the logic in this.
If all you follow is the PC market you are missing the much, much bigger world out there. AMD's dumping their handheld division right before it exploded in popularity is the biggest business mistake they have made in many years, $65 million to Qualcomm which has already made *significantly* more profit then that back on Snapdragon alone(which is an ARM/ATi designed SoC). If they had held on to their handheld division and continued to develop it, they could have a potential market larger then either their CPU or GPU business within the next few years; unfortunately they exited the market right before it moved directly in line with where their designs were perfectly suited.
Current analysts projections on the broader market versus PC shipments have PCs falling to likely well under 10% of the CPU market by 2020. How does this all tie back around to Fermi?
The Fermi design gives them a huge lead in the workstation/crunch rack over Intel or AMD- even Intel's own PR talks about how badly they get beaten(I'd hope Intel fired the idiot who released that one

). On the other end of the computing spectrum, they are pushing platforms that are going to compete with Intel's Atom line in the MID space. Right now, MS has three different OSs running on CPUs made by nVidia- the fastest growing OS by a long shot right now(Android) is also running on nV CPUs. While a lot of people seem to have a laser like focus on how AMD and Intel are going to squeeze nV out of the PC space, they fail to notice that nVidia is right now positioned to do very well in every other computing market while both Intel and AMD are decidedly not(outside of consoles which AMD is still looking strong for outside of the handheld market thanks to their boneheaded sale).
Fermi designs, moving forward, are nV's best bet when they try pushing up from the bottom moving forward. A Netbook with a Tegra4 chip could have more raw compute power then a PentiumD using less then a watt(nV uses the workstation market to figure out the best approach, then scales small units down to put in the Tegra line). That kind of squeeze coming up from the bottom could be a problem for Intel and AMD. General users compute power needs aren't going up anywhere near as fast as they have in years past, and everyone involved in the industry knows it. What do you do to make a desktop PC compelling when a tablet can do everything they use their desktop PC for(many users are *already* getting this with the iPad today- it's not like it's some far off pipe dream)?
All of this assumes that nV can execute. People who follow only the PC market may mistake lead time with failure on the part of the Tegra line, but the design turnaround in the ultraportable market is *FAR* longer then what people are used to on these boards. Tegra2 is going to be a major player in the ultraportable space in the not too distant future- anyone can simply follow Engadget for a couple of weeks and read all the news and see that that is simply a statement of fact.
If they can continue to push their way both up and down in the ultraportable market while continuing their high end dominance with Fermi type parts they will be more then comfortable with their market position. Those two factors are both big *ifs* to be sure, but that they have been ready for this chain of events to happen for years can not be doubted. They have everything in place they possibly can to be ready to exit the PC market entirely within the next decade and potentially be far larger then they are today(not that that I expect that to happen at all, just looking at it from a positioning perspective).
