Windows 32 or 64

WINDOWS 32 OR 64?

Windows 32 confines most users to about 3gb of active system memory, with perhaps 1gb for internal system functions.

Windows 64 allows use of much more than 3gb, depending on the system, and 64 may be a prudent migration for Windows 7 users, as matters seem to be headed.

Because, considering the way web apps, stand-alone apps and other, “camp follower” apps like media player and update reminders sprawl over system memory, it seems Windows was never designed for efficiency, only to serve as a power-hungry shell and circus tent for a raucous crowd of developers of varied talent. Of course, I am being too kind…

My questions–

1. The Opener– Windows 64 is somewhat more attractively priced, but are there any obvious negatives to moving from 32- to 64-bit Windows? (Presuming the CPU is OK with 64-bit and I have enough space)

2. My reading tells me Windows 64 easily accommodates 32-bit Windows applications, in most cases. But does this impose a penalty on a system mixing 32 and 64-bit Winapps– ie. should I keep only 64-bit apps on the 64-bit partition?

3. Because many users desire to keep the home / office network as it is, and add Windows 64 one box at a time, what network disruptions should be expected? For example, will a system backup that works well across a 32-bit network (when run to or from a 32-bit machine) now have problems with the 64-bit box?

4. As a general principle, is it better to convert all network boxes to 64-bit, instead of leaving some as they are, with 32-bit?

5. What has been your favorite source of really useful information about Windows 64 problems and fixes– both migration and “gotchas”?

6. What led you to migrate to Windows 64 (of any Windows version)?

7. Were you completely successful on first try?

8. Are you happy with the results– was it worth the effort (really?)

Eight questions is a big target, so attempt as many as your knowledge and stamina allow. Thanks– many others will benefit from your experience !
