The apps mentioned are popular, but few needs *all* of them. One can do without KDE and gnome, run a nice lightweight window manager instead. Take the kde/gnome performance hit only when you actually need some kde/gnome app. Not every day. A nice windowmanager like icewm of fluxbox brings the login delay down to 3s or so for me.
Openoffice has lightweight alternatives for every task. (abiword,lyx,gnumeric, . . . ) Strange that this bloated sw is as popular as it is, given the many alternatives. Not something I use every month, and I use linux exclusively for my office tasks.
Another alternative is to profile the slow apps and improve them. Fix algorithms, optimize stuff.
The slow boot is fixable by: 1) run boot scripts in parallell instead of sequentially - somewhat experimental but helps. Especially if you can bring up X before slowest stuff completes. 2) Don't run what you don't use/need! Don't install everything and the kitchen sink just because it is free software. I am guilty of installing too much myself, so I suffer 40-second bootup time. But I don't reboot my office pc every week, normally I only have that 3s login delay.
