Sounds like large packages. 1GB (as you say later) is probably a
reasonable guess.

The 2*RAM rule of thumb is usually followed by "but not more than 512MB,
usually". I can't imagine what you'd be doing (or rather I can, but find
it unlikely) that would require more than 3GB of memory. You can probably
get by with no swap space, but 512MB is probably more than enough. I have
768MB of RAM, and 2GB of swap, spread across 2 hard-drives on different
ide buses (for optimal performance), and *rarely* use more than 40MB.
That's just the kernel trying to be efficient. Without X, my computer uses
about 220MB of RAM, running all the services I need (httpd, sendmail, ssh,
etc). With X running, it will use (via buffers and cache) all the
available RAM, and still rarely swaps. With a third more RAM, you almost
certainly don't need (much) swap space unless you are doing some
ridiculous memory usage.

The point is that some things take a lot of space. OpenOffice.org takes
about 300MB by itself. Things like apache and database servers may take a
lot of space. *BUT*, if you add the 2GB you were going to use for swap to
your root, you should be fine.

If you are only using linux, your personal files should really go under
/home/your_login any way. It sounds like your laptop is something like 1GB
RAM / 36GB hard-drive? I'd do:
/boot 100MB
/ 6GB
/home 29.9GB
This should be sufficient and appropriate for most needs.
