Even though they are altering their entry-level desktop CPUs drastically, Intel has recently changed their mind regarding one particular model. They will still be offering the E2140. As a dual-core, 1.6GHz Conroe-based chip, it has many others that have overlapped and replaced it in terms of performance, especially in the dual core arena.

That aside, Intel still sees enough demand for it to keep it around, despite initially planning to phase it out. The reasoning seems to be competing with AMD's lower-end of dual-core CPUs:

The reason Intel has decided to keep E2140 in the market is to defend against AMD's Athlon 64 X2 3800+ and 3600+ processors taking market share in emerging markets, the sources commented.
The price of the CPU is currently fairly low, but will dip as low as $64 next month. However, that still does not compare to an OEM variant of the 3600+ and 3800+ X2s, which have been seen for under $55.
