64 BITS COMPUTING

Do anyone know the PC market trend regarding the 64 bits machine? When do they predict 32 bits machine will be obsolete? Or when do they predict 32 bits computing will be obsolete?

Currently Microsoft is developing Windows 8 to support 128-bit, so it is obvious that trends are going to trade off 32-bit computing, but it is not easy to do it in one or two years, it will take some time, but not before two years from now.

Even though most new systems are x64 (64-bit), most of the apps (including Microsoft's) are x86 (32-bit) and run fine on x64 systems.  

Given that Microsoft extended support for XP = 2014; Vista = 2017; Windows 7 = TBD, x86 will be around for many years to come.

As for the x86 computer itself, I think the exponential sales increase of x64 systems will result in system manufacturers curtailing then eliminating new x86 systems in within the next few years or sooner.

Agreed.  There are very few 32-bit only machines on the market right now.  Nearly all are 64-bit but capable of also running 32-bit software.

32 bit architecture cannot handle more than 3GB of RAM or so.  With all of the new resource hogging apps out there now, 3 gigs just wont cut it in a few years.
