My take on the list of points:
1) Resolution has been a bit of problem for me, in Hardy. Only after I install the binary driver from nvidia's site I can get proper resolution (8500gt here).
2) Boot manager point is completely crap. Sure there are better boot manager but lets just stick to something thats most widely used just in case the new users need help when they screw up their machines.
3) Mounting - completely agree.. this sux.
4) Agree on the installation part fully.
5) Sound? I think PA was a bad choice. OSS4 is much better, imo. But then its only my opinion.
6) Networking - I haf only one complaint... Network manager.. thats the biggest piece of **** on my ubuntu box.. again.. personal opinion.. (and thats why Mac4Lin doesn't support NM icons.. prolly never!)
7) Power management - fully agree.. suspend/hibernate never worked for me over the past years on various laptops/desktops.
8 ) Email - Ubuntu should also offer to install Thunderbird. Not a big issue tho.
9) Not possible to generalize the 'problems' ...don't agree.
10) Checkinstall?? Damn.. and the guy wants to "standardize" it! lol..

---------------------------------------
Points I think which should be included:
1) As said by Shashwat include a small ogg video - Ubuntu tour.. telling users where the most commonly used settings/programs are located (menus).
2) Ask the user to configure network and printers.
3) Ditch the bullshit network manager and include WICD instead.
4) Include the a tool for mounting ISOs.
5) Include bluetooth tools out of the box.
6) Include a download manager.
7) Include out of the box samba support.
8 ) Include apt-on-CD.
9) Replace the boring and intimidating brown interface with a better looking default UI (like suse/fedora/mandriva etc.)
