Computers are getting faster, but also more memory intensive. I can not find a laptop with less than 4 or 8 GB of RAM. Modern browsers, such as Firefox, require a 64bit architecture and 8GB of RAM. A 32 bit platform is not enough now a days on systems with more than 4 GB of RAM. A 32 bit core now is like 640K of RAM in the 1990s. Even in the embedded world ARM is going 64 bit with ARMv8. Secondly, the i386 port is unmaintained. Very few developers run it, so it doesn't get the testing it deserves. Almost every user post or bug report I see from a x86 compatible processor is running amd64. When was the last time you booted i386 outside a virtual machine? Often times the build works for amd64 but fails for i386. Finally, others are dropping support for i386. Windows Server 2008 is 64 bit only, OSX Mountain Lion (10.8) is 64-bit only. Users and downstream vendors no longer care about preserving ancient hardware. I hope this email is enough to convince you that on this date we should drop support for the i386 architecture for 10.0 to tier 2 and replace it with the ARM architecture as Tier 1. -- Eitan Adler
