Unless you root the Intercept you will have issues like missing calls because of lag. I can understand Samsung wanting to make phones as cheap as possible but since they already know the shortcomings of this line of phones why not bump up the RAM to 512mb? That couldn't have increased the price too much and the performance benefit can be seen in phones like the Optimus line.
I think Samsung/boost/sprint chose to do to boost what they are doing to Virgin. Release any cheap Android, then a few months later release a much better Android to get people to re-buy, then a few months later release a more recent phone to still even more. They have already told Virgin customers the next Android will have 4.1" screen and 1ghz snapdragon. So it los like you guys have about a year before you get a really nice Android.
