I would like some thoughts on types of scanners everyone is using. With the arrival of USB2, the new HP 4670 scanner would be nice. Reviews indicate some graining and a shift to yellow. Would like to scan slides and negs (another feature of the HP). Always been under the impression USB scanners are like molasses (especially given older USB speeds). Slide quality would obviously not match a dedicated film scanner but... Current scanner connects via firewire & I'm happy with speeds but, as optics progress resolution increases as well. Again, not looking for pro results, just satisfactory for home use. Rod
