Yes, I only use aptitude from command line for things such as
aptitude purge ~o
which are impossible to achieve with apt-get alone and not easy even if
you combine it with other tools.

The interactive mode is very powerful once you understand how it works
and remember the keystrokes.

aptitude can and is used for day to day operations by at least one user
(me :p ), but I also try to use the best tool for the job. For example:
$ time aptitude install base-files
Reading package lists...
Building dependency tree...
Reading state information...
Reading extended state information...
Initializing package states...
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
real 0m3.162s
user 0m3.056s
sys 0m0.092s
$ time apt-get install base-files
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
real 0m0.363s
user 0m0.004s
sys 0m0.000s
As you can see, aptitude takes 3 seconds just to tell me that I'm not
root and this is on a somewhat capable machine (Intel Dual Core
T2330@1.6 GHz with 2 GB RAM), but I have it running all the time anyway.
On my PIII 500Mhz aptitude takes almost three times as long, while
apt-get doesn't have a noticeable (for me) increase.
Kind regards,
Andrei
