An I/O bound app is an app that spends most of its time waiting for input
from peripherals. Most desktop software works with user generated input
from keyboard/mouse.
In simple English: if you have to type or click a lot in your application,
you won't benefit a lot from 64 bit. This is oversimplified.
For over a year? Then you may consider yourself a 64 bit newbie. It is
only in the last year or so that 64 bit has become a bit usable for the
desktop. Some of us have been tinkering with 64 bit for 3 or 4 years, and
have built user experiences. Some good, some bad. Again, CPU bound apps
are great on 64 bit. I/O bound? Not worth typing 'sudo zypper in
foobar32'.
No.
It depends on hard work that programmers have done over the years to
improve browser plugins for 64 bit.
They solved all those problems before you started using 64 bit, so you
don't know about all the Bad Things that can happen. That's not your
fault.
Those of us that Have Been There (and Bought The T-Shirt) are more
careful. If it (our current 32 bit installations) works, don't break
(upgrade to 64 bit) it.
As always, YMMV.

i hv Core 2 Duo processor and 2 GB memory on my notebook and i m going
to have a fresh install for opensuse 11.1. From opensuse website, it
says for my spec, I should go with 64 bit version. What is the plus
minus of 32 bit and 64 bit?? Should I go with 64 bit?? Could 64 bit
runs Compiz?
Your processor is designed to work best in 64 bit mode, and you will only
get
the full benefit of the extra registers and 64 bit instructions with a 64
bit
operating system. The plus is significantly better speed in heavily
processor
bound apps (graphics, scientific, etc.).

I've been running 64 bits on my main workstations for over
a year.

No problems at all related to installing 32 bit libraries
to support the rare 32 bit code I need to run (games like Doom 3, Quake 4)
various other things via wine, and multimedia codecs. YaST handles it
automatically. The NVIDIA installer even provides 32 bit compatibility GL
libraries.
Early on, there were problems with browser plugins but I haven't noticed
any recently. I guess it depends on what you browse to.
No.
