As promised (threatened?), Philippe Winthrop of the Enterprise Mobility Forum and I exchanged views about enterprise mobility this morning during SAP’s inaugural Tweetchat.

I think it went pretty well: we answered almost 30 questions from and went for a full hour (we were originally scheduled for just half an hour).

In between, Philippe and I cracked wise. For those keeping score at home, Philippe aka The Heel (bad guy in pro wrestling jargon) bore the brunt of Eric The Face (good guy)’s verbal body slams (I kid, I kid).

If you couldn’t make it this morning and are interested, below is an edited transcript of our discussion. Thanks to SAP’s Kevin Cassidy (aka @SocialKev or @SAP on Twitter), who also served as our moderator.

It’s replete with links and theme music: I entered the Tweetchat to the thundering keyboards of ‘Sirius’ by the Alan Parsons Project, aka the Michael Jordan-era Chicago Bulls entrance music, while Headbanger Phil chose the portentious bombast of ‘Welcome Home (Sanitarium)’ from Metallica.

Crank up one of those songs as you read on…
