It took me 1 hr 25 min on a Core 2 2.4GHz with an SSD, on 0.7.1. After block 189205 (or block 193000 with tricks) your Bitcoin will be again connecting to the network normally to get 2GB more blockchain after the torrent's last block.

Are you saying good hardware will cut the launch time? (well, obviously)....I mean, I always thought the bottleneck was slow internet speed to download said blockchain...

-----------------------
Bitcoin.org client v0.7.x
Estimate for first-time use, syncing the blockchain. (Estimates obtained via wild-assed guess)

Poor hardware using bootstrap.dat: 2 days 6 hours
Poor hardware with fast internet: 2 days 8 hours
Poor hardware with slow internet: 2 days 12 hours

Fast hardware using bootstrap.dat: 1 day 1 hour
Fast hardware with fast internet: 1 day 2 hours
Fast hardware with slow internet: 1 day 3 hours

-----------------------

Bitcoin.org client v0.8 (Not yet released, or even near release-candidate)
Estimate for first-time use, syncing the blockchain. (Estimates obtained via wild-assed guess)

Poor hardware using bootstrap.dat: 3 hours
Poor hardware with fast internet: 4 hours (?(
Poor hardware with slow internet: 5 hours (?)

Fast hardware using bootstrap.dat: 1 hour
Fast hardware with fast internet: 3 hours (?)
Fast hardware with slow internet: 4 hours (?)

(With "poor hardware" I'm referring to slower, modern systems. I'm not referring to your P4 or an atom-based netbook.)

So, I hadn't updated my bitcoin blockchain in a long time and it was taking forever to download. Then I found out about the Bootstrap.dat method. I downloaded it and put it in the bitcoin folder in my application support directory. I had deleted the whole directory and moved my wallet.dat outside of the folder in an attempt to restart the whole thing. Anyway, when I started it up it said "importing bootstrap blockchain data" and it has said this for about an hour now. Is this normal for it to take this long?

Very little of the time in synching the blockchain is spent on downloading the blocks and most of the time is spent on CPU and I/O. Because you have bootstrap.dat locally, what little time was spent downloading the data is cut but the rest remains.

It can take a day or more.

Version 0.8 isn't ready yet but it uses a completely different architecture and knocks that down to about an hour, on good hardware.
