The biggest reason *not *to upgrade to Qt 5 (for me, anyway) is that Qt 5
SDK won't install on CentOS 5.5 (my primary development workstation - 3
monitors, 12 GB RAM, etc) and CentOS 5.5 isn't exactly an old distro.
Here's the results trying to install from a fresh Qt 5 installer download
just this morning:

[root at josiah-desktop Downloads]# chmod +x

[root at josiah-desktop Downloads]# ./qt-linux-opensource-5.0.1-x86-offline.run

[root at josiah-desktop Downloads]# uname -a; lsb_release -a
*Linux josiah-desktop.pci.local 2.6.18-194.26.1.el5PAE #1 SMP Tue Nov 9
13:34:42 EST 2010 i686 i686 i386 GNU/Linux*
*LSB Version:
 :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch*
*Distributor ID: CentOS*
*Description:    CentOS release 5.5 (Final)*
*Release:        5.5*
*Codename:       Final*

Of course, I would *love *to be told I'm an idiot and it's really quite
simple to do that on CentOS 5.5 (e.g. < CentOS 6) - and all I need to do is
"yum install blah blah blah" ... believe me, I've spent many an hour trying
to install this - ever since Qt 4.8 came out, in fact, and qmake started
not building during the install - all the way till now, when the installer
itself doesn't even run.

Anyway, just my thoughts - cheers!
