As a longtime slicehost customer, thank god for competition. Slice has been slightly overcharging for memory (my current bottleneck). I also don't use any of slicehost's (admittedly great) tools.

I'll probably think about reevaluating my server costs (about 300 mo) if slicehost doesn't boost their memory offering in the next few months. Especially using chef for scripted infrastructure, all I'd have to do is change my ip list and rerun.
