I am all about cross platform these days. S4 GE phone, iPad, MBP laptop, and a windows desktop powerhouse. iTunes Match sucked when I used it last but its been a while.
I've had it since launch, and it's always been pretty buggy. But for the last 12 months all issues I had (libraries getting weird on one device, streaming choking a bit sometimes) have all been fixed, so I'd gladly recommend it now. 18 months ago? God no ;)
