Boxee announced back in December that its PC client would be shuttered, and the time has finally come: Boxee will remove all copies of its app for PCs by the end of today. As GigaOM reports, Boxee VP Andrew Kippen confirmed that the company will officially kill the PC client. In his original announcement, Kippen said that the future of TV will be driven by the Boxee Box and other connected devices, rather than PCs — the move makes sense, considering that even Microsoft has shied away from the HTPC crowd by focusing on developing the Xbox 360 ecosystem. Of course, Boxee's business concerns won't provide much consolation for early adopters.
