That is in theory. In practice there is a bug with the 0.8.0 version where only ~70K blocks are loaded from the bootstrap.dat file instead of 200k+. This is my experience and you can read about it on this thread:
https://bitcointalk.org/index.php?topic=153120.0I assume you are responding to "I found out that using the new version 0.8 it only takes a couple hours", since nothing I posted is in theory.
There is no bug in Bitcoin, anyone that has taken the time to actually file a bug report and follow up with testing after having such problems synchronizing the blockchain, it is determined that there are hardware problems with their computer causing inconsistent or unrepeatable errors.
The OP hasn't specified his internet connection speed so how can you compare his experience with mine? Maybe his connection is much faster.
Anyway there is nothing wrong with my computer. It is rock solid stable.
