Like to Zeke's post above
I think perhaps because I have been out of the technology loop for a couple of years now then I guess I have just lost track of what has been happening.
However I could also say I have been dis-encouraged by the lack of development. I haven't investigated what SandyBridge is because I haven't been watching technology as much as I used to. I don't know what the difference between Windows 8 and Windows RT is, again because I am not really interested at the moment and by the time I am, they'll all have new crazy names instead of calling them something sensible, like it used to be

Thanks Windows Vista!
I remember my family PC being a 333Mhz processor, then being upgraded to a 700Mhz odd which was out of this world. From the 333Mhz to the 2.6Ghz of today's world, I am certain all that happened over about 2/3 years. In the last 2/3 years it seems we have found the limit of what can actually be achieved at the moment.
I guess it also boils down to the fact when I do upgrade, then it will have to be everything at once to see the full effect, which I am all game for but when I don't use the desktop PC as much as I used to then I am starting to think if it is worth the money and time to build something that won't be used very much at this point in my life.
USB 3 is the future, I agree but when I have very little that uses it, then it will just be a bit of fun. My memory sticks are all fine and I don't see myself throwing away the external hard drives any time soon either. My digital camera is probably USB1 and still works brill - I tend to take care of my technology
Dual core, triple core, whatever core, the difference between my first PC (single core) and the second (dual core) wasn't that noticeable in the grand scheme of speeds. However I know SSD would improve this greatly but something irks me about putting brand new tech with an older system.
Not an anti-windows 8 fanboy, certainly not. I am glad they are pushing through with their OS despite the negativity and slow uptake. From what I have experienced, how it was first marketed (certainly in the UK) and the complete difference in how one would use it as it's meant to be, I am just of the opinion it was built for touch screen devices and would be more at home on one.
