I use toggl for timetracking, and am currently investigating bullet and xero for accounting/invoicing. Can't recommend one over the other just yet, but preliminary thoughts are that bullet would be better if you don't currently have an accountant, whereas xero is a tool to empower your accountant.
The colours are beautiful, but the portfolio items are too small. Perhaps an option to zoom in to see the work?
Also, if you don't have the divX player on automatically play (as I don't) then your stuff has a big gray box over it when you first click in.
Love the click out tabs and the illustrations are great!
