Don't do it!
Just think of all the money you have spent, and all the fun you have had. When you ebay the stuff you won't get that money back, and the chance of having more fun is gone..
Then when all things passed, and you get the bug again (cos you will
) then you'll have to spend again on all new everything.
Best thing to do, is just stop spending, keep you stuff and bring it out when you need to get away from everything. Then when the time comes to jump back in, you may just need new cells - then you can choose to grasp the latest technology at your own time.
