Actually, the trend now is in de-bloating software. Everything from Windows, to Office, to even high end Adobe software runs faster now for the same tasks than they did 5 years ago, and with Win8 we are going to see an acceleration of this trend as software is going to be designed for tablets and phones as the primary medium instead of desktops.
High end Adobe suites will ever require more hardware for the new features that they come out with (like automated motion blur removal in the new Photoshop), but for simple edits in Premiere or Photoshop, it will run faster on the same hardware compared to the older revisions because they are making the code tighter, and these new engines are more intelligent about resource handling. These new softwares are not so efficient that they are 'amazingly' faster than their previous revisions, but it is a trend that people enjoy, so software makers will continue it.
I do have a fear of the death of the PC though:
I think when the C2Duo/Quad came out we finally saw the first CPU that could in fact handle 90+% of people's CPU needs. Yes, to do anything exciting it needs to be paired with an SSD and a GPU, and have fast internet access, but for everything from web browsing, all the way up to mid-level gaming, and all the way in the other corner of light to moderate photo and video editing, these 4-5 year old CPUs are still enough for most people today, where as every generation of CPU before it hit a wall ~3 years in, so most people upgraded their PC every 3-5 years.
The way things stay cheap is if there is a huge demand for parts, and said parts can be made cheaper in larger mass. What we are looking at right now is the 'life extension' of the desktop, not the death of the form factor. But if a 5 year old machine can do everything that most people want to do (and likely will continue to be enough for the next ~3 years), and if current machines are easily 3x more powerful, then how long will current gen hardware hang around on the market? 12 years? 15 years? with only minor repairs for things that wear out like HDDs and power supplies (even cheap computers have solid caps, so even crap mobos last a long time)? If PCs begin to last so long, then we will begin to see a dramatic drop in PC sales, which means less production, which means more expensive parts, which then leads to even less sales.
My fear is that with the rise of the tablet and smartphone, that people who just purchased, or will soon purchase a computer, will never replace it. In 10 years these smaller form factor technologies will simply be enough, so the ATX form factor will be relegated to extreme game systems, high end workstations, and home servers, and all 3 markets combined is a very small fraction of today's PC market. With so little incentive for parts makers to continue making parts, the parts will have much higher price tags, and become much harder to come by, and that will be the death of the PC. I do not think the threat is imminent like some do, but I do think we will see it at some point in the next 5-10 years.
I think you are (unfortunately) wrong on the console end of things too. Yes, the PC will have a clearly better experience, but in reality, people buy things based to thresholds of experience based on their medium of choice rather than purchasing for bragging rights or to have 'the best' experience possible. Current consoles suck, not because they are not upgrade-able like a PC, but because console makers had no idea that 1080p would catch on like it did, and they are only designed for moderate 720p gaming. This next gen of consoles will be able to play high end 1080p games at 30fps very well. While the PC will offer faster load times (or no load times), better mods, and higher resolution/fps screens, the average joe will not care because they want to see their game on the big 55" high contrast TV, not the relatively small but higher quality 20-28" monitor. And for that 1080p 30fps environment they will choose the game console every time. The difference this time is that the console will be adequate for the medium, where the last gen frankly was not up to the task. The only real hope for the PC game rigs is for 2K and 4K TVs to come down the pipe in the next few years (which may happen as soon as this Christmas), or for multi screen gaming to take off (which is unlikely).
