Or faster

Samsung screwed the pooch using old slow tech everywhere except the processor. If they had left their legacy mindset behind, they easily could have had the fastest Android device on the market.
The speed issues on the Hero can be fixed. Samsung's poor bus speed can't, and it's incredibly stupid on their part. They have the best display on the market, hands down. They have a very fast processor. Then they bottleneck it all down like idiots.
EDIT*
One thing to add - actual hardware defects are pretty damn low on the Moment as well. Add great quality to the list of what they ruined by not stepping up their game with a better designed mainboard and using 1990's file system architecture.
