How can I benefit from using Skype and Google Voice?

I am currently trying to figure out how to take advantage of this whole google voice/VOIP/SIP revolution. Here is what i’ve come up with thus far, let me know if there’s a better way. (cause there probably is)

(Outgoing)
I have a $3 a month skype plan that allows me to make unlimited (fair use =10,000 minutes/6hrs a day.) outgoing calls to landlines and cell phones in the US via skype application on my laptop or iPod touch within a wifi hotspot. The number shows up as “unknown caller” or something to that effect, to get caller ID, and a number that people can call me on, would cost $30/year.

(incoming)
(this is where is gets messy)
If someone calls my Google Voice number, it is set up to forward to my cell phone only during the free anytime minutes (7pm-7am), if it’s not a free calling time, the call gets routed to my Gizmo number that is set up within Google Voice, from there, the call is routed to my Skype Account, so that I can receive the call on my laptop or iPod Touch via Skype (if the iPod is on and I’m in the skype app) and if I am in a Wi-Fi zone.

(what then?)
If any one of those things fails, (not in skype app, not in wifi, dont have lappy out etc) the caller can leave me a GV voicemail. Which is then transcribed to and sent to my cell phone via text message. (all for free with unlimited texting plan). At this point I can choose to respond to the caller with my cell phone, call my GV account from my cell and listen to the voicemail, (uses cell phone minutes), OR I can get to WiFi and listen to the voicemail and return the call via skype.

This is messy. But it works. Now here is my question.

Can this setup be made better in any obvious way? Am I paying the $3 a month skypeout fee for nothing? I am too involved in this to be able to see the whole thing all together. I need a fresh set of eyes to look at this.

Feedback appreciated.
