Hi Bob,
Thanks for your input as well, The main reason for asking was because I started building a data managing application for companies to manage paper work and would work well with medical companies or smaller companies that want to keep things organised and also have features like mailing to users and signing work and tracking progress and the whole import and export thing and it got bigger than I expected while building (I did everything on my own) - and because of work I had to put it on hold. When I got back it noticed the polymer updates and although I was following the blogs and YouTube subscriptions on the updates, I saw its not going to be an overnight thing. Most of this things I still need implement now but I was put on hold because of the migration
I guess If I really want to use this and if I want to be safe and be sure to always have support from the community then I best go through it. No-one ever said they made a mistake when making sure their apps were future proof.
Ill keep you posted but good luck on your adventure too man - all the best!
Regards
