I like the Merlin, and think that it will be a good source of income for side jobs in the future. It will be around for at least a decade, and since no one will be factory authorised dealers, and Avaya Global services will be the only authorised service channel, Business Partners will no longer be able to get parts cheaper than all of us doing side work. Soon you will be able to purchase refurb parts for much the same price as the BP you now most probably work for.
If I am wrong about these facts let me know. Now some may have non-competes, but most BP's will be focusing on the IPO, so they may lose interest in ongoing service to equipment they can not get new parts with avaya warranty on. Every tech with Merlin experience will most probably be able to undercut a BP on labor pricing, and compete on parts pricing. If you have IPO experience, and know Merlin, it may be time come April to go independent and subcontract for IPO implementation to BP's, while competing with them for Merlin. Also, get up to speed on the IPO as BP's will need techs with product authorization to implement. Many BP's from what I hear have not entered the IPO market yet, is that true for your employers?
You do not always get what you pay for, but you never get what you do not pay for.
