Domain? Or not to domain?

Pondering, pondering.  I've been tossing about the idea of buying a domain name and then making personal email accounts.  Should I????  I use wordpress.org for work websites and have gotten pretty good with it.  There are some pretty cool plug ins that I can't use on my wordpress.com blog.  BUT....is it worth paying for?  Should I just stay with the constantly available from anywhere free gmail or live account and forsake any personalized email?  If I decide to let my website go, then I'm out my personalized email.  All these things run through my head constantly.

As I put them on paper, I'm not thinking, just STOP!  Stick with the freebies.  I love tech but I'm not the big tech guru as evidenced by my blog that doesn't get updated as much as it should.  I would love to keep a better record of what runs through my head.  Possibly in the future a domain name.  But for now I need to just create my landing page that has links to my daily places to visit.....found symbaloo recently and may use that. 

 .....sigh.....more decisions.  Gotta love ever changing tech!
