I'm ready to upgrade from my S3 with a broken screen. Most carriers in my area are offering the s5 for $150, or the Alpha for $0 on a two year term. I'm looking for advice, im not the most well educated on these devices. I get they're a couple generations removed from the top of the line.my girlfriend has an s5, nice phone but I like the premium design of the Alphas outside. As I understand it, most agree the Alpha is just as good as the S5, apart from the smaller and less advanced screen. I can live with that. Most reviews I read say the biggest draw back was the similar price to the s5 at launch. My real concern is how long will this device be supported with new updates to the OS compared to the S series. Looking for buying advice. Is the alpha a steal at $0, or is the s5 worth the $150?
