Epilog:

I kept using the service because even though there was no new content available (ever!), there was enough content there to satisfy my $7.99 a month.  This past month, I was billed as usual, but then today, I saw a credit for $5.06 on my card and wondered WTF?  So I go to Guitarport's web portal and sure enough, they are shuttering it on 31 Jul 2012.  The good news is that I get a free Spider Online membership, whatever the heck that is.  From what I've seen, you need a Spider amp and I only have the PODxT bean myself so whatever.  Burn me once shame on Line 6...they won't burn me for another service that fizzles down the road I guess.  The other bit of good news (better news actually IMHO) is that they also comped me the POD Farm 2.5 plugin gratis, which should be pretty nice as long as it supports the 3 model packs I bought for the POD...I can already see a minor nightmare in store for me in switching those packs from my hardware unit to the POD Farm plugins...we shall see.

Too bad overall IMHO, I liked GuitarPort and used it fairly often just for the fun factor and I did pick up several new songs along the way.
