Unfinished (for) Business
My issue with most Google products isn't the execution itself, it's the polishing afterward. Google seems to have turned into an art form the process of creating a product but never quite finishing properly. Take Google Drive as an example..it's an improvement on Dropbox in terms of the free space on offer, but every other aspect of the service sucks in the most basic terms (the interfac online, the client software, the sync), and that example is a product that Google could easily have "borrowed" some ideas for from its competitors because it was so late to market!
If you then factor in Google Docs, Android, Chromebooks and that awful Nexus Q (http://www.theregister.co.uk/2012/08/01/nexus_q_preorders_halted/) thing that they actually halted and revised they don't look ready for enterprise at all.
