Windows Vista x64 and Fujitsu Hardware

No x64 SupportOké. I have this Fujitsu Lifebook E8310 from work (we're not allowed to use Apple hardware :( ). This piece of hardware was released with an OEM version of Vista Business, but work-related circumstances forced me to install Windows XP at first. Now about 1.5 years later I wanted to try the included Vista Business version, and since I have 4GB RAM I installed the x64 version. What's the use of the additional RAM otherwise?

B.t.w., you may see this as an addition to this posting about Windows 7.

Installing Vista Business x64 isn't the problem (so this is no rant against Microsoft), but trying to get every piece of (integrated) hardware to function properly is something completely different. Vista is on the market for ages (or so it seems), and still NO decent driver and application support for the x64 versions (example 1, 2, 3 of an endless list). What the f#ck is wrong with hardware (and software) developers? 64bit (client) computing is available since the release of Windows XP. Every new piece of WINTEL hardware released in the last two years has (multiple) 64bit cores or CPU's.

x64 Operating Systems mean that you have more memory at your disposal to do bigger (memory consuming) tasks. Windows-based 32bit systems can only address up to  3.2GB of memory.

As long as this will continue to stay this way, I'll continue to rant about this, and personally not buying (or advice) any more WinTel hardware (or software).
