Intellij and firefox seem to use the most memory.
(Also, this chip is officially only i586 compatible, so obviously there is no PAE and other fancy stuff either...)

People using older hardware should switch desktops anyway, unity/gnome3/kde4 are heavy weight. Someone with a processor too old to support 64 bits should switch to Xubuntu or Lubuntu, also to avoid the non pae issues.
Yes it should be the default. Been using 64 bits for 5 years don't see the reason not to unless your hardware can't handle it, which means an old p4 or such which are better served by a light desktop.
Agreed. I've been using 64-bit for several years now, and it's been completely painless for the last few releases. There's also been some benchmarks only a few weeks ago which showed that 64-bit was faster than 32-bit in several areas, so there's other benefits aside from support for more memory. The biggest difference, as far as I see it is going to be:
* Download Ubuntu 11.10 32-bit (recommended)
* Download Ubuntu 11.10 64-bit
will be changed to
* Download Ubuntu 12.04 64-bit (recommended)
* Download Ubuntu 12.04 32-bit
The 32-bit version isn't going anywhere, it's simply not the recommended option anymore.
