So what will you guys do when you eventually move to a 64-bit system? I personally don't anticipate a move to a 64-bit system for another 5-10 years. I think 4Gb of RAM will be more than enough for my needs for at least the next 5 years. I am currently running on 2Gb of RAM, and I can do everything I need to with lightning speed. In fact, my computer/system is approaching 3 years old now, and it's still lightning fast and responsive with every program I personally use. I don't anticipate to purchase a new system for at least another 2-3 years. When I do, I will most likely move to a 32-bit Windows 7 platform with 4Gb RAM and whatever new generation processor is available from Intel. However, I can see that I will probably eventually move to a 64-bit system (unless I completely lose interest in computers, which might happen...10 years is a long time!). And so the question is what security software would I use then on Windows? It seems that my most favourite security application Sandboxie will never support 64-bit, period. I know that a lot of you guys out there favour DefenseWall and Malware Defender greatly too, but neither will support 64-bit either. So what will you do? I am aware that this is all quite hypothetical (especially from my view-point, since I don't intend to use a 64-bit system for at least another 5-10 years...I mean, the world might come to an end by then haha), but I am just interested to see some opinions here. Would any of you be willing to ditch DefenseWall in order to use a system that utilises more RAM? Would any of you be willing to ditch Malware Defender for the same reason? Or are there any other perspectives out there? Will we perhaps see Windows 64-bit systems become more compatitble with security software like Sandboxie, DefenseWall and Malware Defender in the future?
