This has been my solution for the last couple of years, and it's actually not that bad.  It does seem to take much longer to sync than bitcoin, even though the blockchain size is under 200GB, but once synchronized it doesn't use up much in the way of processing or ram resources.

I don't have any mobile monero wallets installed either, but I believe MyMonero will allow you to connect to your own remote daemon which can improve privacy.  I like to have the official monero wallet installed on my laptops, so I can and do connect those wallets to my remote daemon through a VPN, which eliminates the need to have the whole blockchain downloaded on every device I use.
