I bought my 80GB G2 intel SSD from the US on my new i7 system I just built. Buying it from the US saved me around AU$100 and I got it quicker (intel G2's only pre-order in Aussie shops when I ordered mine). I use it for the O/S and apps, and have a 1TB drive for data.
It is pretty quick I must say, sequential reads about 250MB/s compared to 75MB/s on the 7200rpm 1TB drive, but it really shows it's speed with small random files, where it completely blows the platter disk out of the water.
Here is a comparison of the two (not really fair because it is a benchmark that plays to the SSD strength but anyway
)
