I concur with ArVee on that Sun.
Now, what is the drawback?
The drawback is AMOUNT of MEMORY recognized and useable by the operating system.
You will not be able to use more than 4 GB of RAM with 32 bit.
With 64 bit, you can go up whatever....
Windows 7 professional 64 bit wasn't bad. Took a little bit to figure out but really want; horrible.
You might look at WINDOWS XP 64 bit
Or Vista Home Premium 64 bit.
Just some thoughts.
