Ubuntu Linux: 32-bit vs. 64-bit

I would like to install Ubuntu on my Dell Latitude E5400 laptop which has 4 Gigs of RAM. It is currently running Windows 7 and I want to set it up as a dual-boot system.

My inclination is to install the 64-bit version of Ubuntu in order to be able to access all 4 Gigs of RAM. However, I was just browsing the Ubuntu online help files and they state that "The 32-bit version tends to be easier to use and runs into less problems."

Why would the 32-bit version be easier to use? And what kind of problems is the 64-bit version more likely to encounter?

If your hardware has support to 64 bit so you can install.
My opinion is go with 64 bit Ubuntu. But the problem is
sometimes 64 bit applications will not available. So this is
the issue, if your purpose is only browsing then you can go with
64 bit.

That's a good point, but according to this article you can install a package called "ia32-libs" that will allow 32-bit software to work under a 64-bit install of Ubuntu:

I am using Ubuntu-64bit, no issue, for at least more than 2 years.
1. Almost all software are installed with software center, pre-built with 64-bit support.
2. If you want to run 32-bit pre-built software with some .deb package, you just need a package called "ia32-libs", just like you said.
