Just a heads-up for anyone who might be interested: a native Linux version of UltraEdit has been released: http://www.ultraedit.com/Newsletters/nov09-uex/index.html
It's chargeable ($40 introductory, $70 full price) and I've not tried it yet (I'm half-way through an Ubuntu 9.04->9.10 upgrade, so now probably isn't the time to install it!) but I know there's been interest in a UE-like editor on Linux expressed here before (as much by me as anyone).
I know the majority won't be interested on price/freedom grounds. Personally I've not found anything as good on Linux as FOSS (primarily stuff like column editing). (Since the software is commercial I should point out that I am not affiliated with UE in any way.)
