64bit flash and 64bit Java are rolling well, shame some companies like Canon and Brother only make 32bit apps. The day will come. 64bit FTW. If you still want 32bit with lots of RAM then 32bit+PAE can address up to 64Gb RAM

For VMWare which bit Ubuntu is better?
RAM utilisation should me more on guest machine to running fast.

I am wondering about 64-bit. After looking at the issue for 15 minutes or so, I’d say one should be at least medium competent on Ubuntu before going to 64-bit, just to be sure that one’s own level of familiarity is not the problem.

Well said, Saul.

I realized that going to 64-bit would halve my available memory (almost). Going 32-bit for now.

@Mikkel Kamstrup Erlandsen:

There is now a 64 bit Java plugin available from Sun on Java 1.6, so I now run Firefox 64bit instead of 32 bit as I used to with the 64bit kernel. That was a major irritation but now luckily not an issue any more.

I am on AMD64 and am very happy with it.

I have the AMD64 Ubuntu running like a demon for everything except Gnome and Firefox. I installed KDE 3.5 and try to stay away from Gnome/GTK applications.

64Bit and my Laptop is a LOT cooler, no more heat production!

@egon and generally,

A 64-bit system will use 64-bit pointers, whereas a 32-bit system uses 32-bit pointers. Other fundamental types (size_t) suffer similarly. Therefore memory usage will be significantly greater on a 64-bit system, though egon’s reported 2x seems extreme. So if your system memory is at a premium, going 64-bit will actually hinder your performance.

Opera in beta (9.50…) supports 64 bit now (maybe, and the “stables” supports now too).

2ALL
In my laptop lives intel celeron 540 processor it supports 64 bit, system in 64bit really faster and stronger (checked in media conversions and compilation)
It eats battery about 10% fasters, and what?
In win xp battery lives about 2.5-3 hours (checked at same friend’s laptop), in ubuntu hardy 32bit – ~2-2:10 hours, in ubuntu hardy 64bit – ~1:40-2. Maybe, ive must install that shity suck (sorry, but in comments there is a tendention)?
