I happily pay for Office 365 in my startup which is open source based (PostgreSQL, HTML, CSS, JS, Polymer) just for Outlook and Excel. There are cheap subscription options I think available for consumers. Outlook is for me, far superior to GMail (I’m no MS fanboy, I hate Word and Sharepoint). GMail was fine for a free product, but the thing i hated about it most was that you could not easily sort mail by clicking on column headers such as date/ from / to etc. I could not believe that such a basic critical capability was absent - have they added it now?
