Aptitude installed by default on 13.10?

[Ma Xiaojun]

The situation seems to be:

Both apt-get and aptitude is far from perfect.

apt-get: more secure and stupid
aptitude: more smart and dangerous

Since apt-get has been regarded as default for long, let's keep it?

But seriously, can we fix the known issues in apt-get or aptitude?
They need some improvement. A rock solid backend toolchain is needed
for our success.
