well thanks for all replying to this topic so far. but i have to say I
don't think that 4gb of ram is unreasonable. I will now explain my reasons.
I have just built a new pc. It cost less than £700 - which is not alot for people who want a PC to last at least 4-5 years.
For my money I got:
Quad Core Intel CPU with 8Mb Cache (Q6600)
4GB Corsair DDR2 Memory
2x250Gb Hard Drives in RAID 0
NVIDIA 8600GS
New Case
Corsair 520W Modular PSU
SATA DVDRW (NEC)
All hooked up to my flat screen, running Vista Ultimate and Linux under VM.
Now compare this to my "cheap" server.
ASUS barebones PC - £70
AMD Athlon CPU - £22
2GB Memory - £40-50
1x 500Gb Hard Drive - £50
So my kick-ass pc, that runs things like Video Editing and Photo Editing as well as 3D Studio Max SOOOOOOOOO well, it awesome and put it into comparision my first PC was only a 100Mhz CPU with 16Mb of memory and that cost over £1400!!!
Now my server (running Ubuntu) is a fantastic low end pc to sit there and store my files on all day. And it cost less than £300. This means that in the next 6-12 months people WILL be buying PC's with 4Gb Memory. And when that happens we will need to be ready.
The thing is, you might not use 4gb of memory every day, but chances are you'll be grateful of it when your editing your documents, editing video and trying to surf the net all at once. Your unlikely to need any more ever - unless your a server
So in short. I believe 4gb is the way to go, and more importantly. So will Dell, Acer and HP within 6-12 months.
