Not exactly right,64 bit Vista will run virtually all 32 bit software that is compatible with Vista,it has no legacy 16 bit software support since they removed that from the OS,good thing IMHO another less thing to worry about.
A lot of companies that make Vista drivers are making both Vista x68 and Vista x64 drivers so they can have WHQL cert from Microsoft,Microsoft won't give WHQL unless they submit both driver versions.
I have all the 64 bit Vista drivers for my hardware,even devices like Winfast USB DTV tuner and Color Spyder2Express USB calibration tool(they only took 5 weeks from Vista's official release date,not bad for a new OS).So if you have 64 bit Vista drivers for your hardware its worth going 64 bit for the better security it has and better larger memory handling 4GB and up.
Vista x64 compatibility is very good,here's my list of installed software.
Firefox 32 bit version 2.0.0.3 with java and flash installed
Thunderbird (64 bit version)
Avast Home free (64 bit version)
CCleaner
Quicktime and iTunes
O&O defrag 8.6 (64 bit version)
Nero 7

Spybot
Printmaster 16

Do note Microsoft's next OS is going to be 64 bit only from what I have read.My Vista x64 HP has been solid and all those games work.
One more thing ,software that has problems with Vista has problems with both Vista x68 and Vista x64 in general,so if it works in Vista x68 then a good chance (99.8%) it'll work in Vista x64(not including 16 bit software for obvious reasons).
