You may want to try SmugMug [1]. Easy bulk mangement, simple to upload to using the Lightroom plugin, private galleries if you need them for clients. Even sell prints etc. The iPad app for viewing your own photos was good too.
I was happy with them but in the end went with hosting my own Koken [2] powered site. Its a blog/cms aimed at photographers, but you host it yourself. Again pretty to use with bulk management and Lightroom plugin for uploading.
