Going through this conundrum.
£180 gets you a sapphire screen, a (subjectively) nicer looking case, a ceramic back, aesthetic compatibility with more straps down the line, and perhaps even perks such as being able to have a personal setup with an employee via video chat.
However, it still doesn't do anything more than the Sport watch does, and the Sport watch will undoubtedly hold its value better in percentage terms if one upgrades down the line.
I'm also a student without much guaranteed regular income, so I'm wondering whether it's wise to spend £180 on just a bit more bling. I could afford it, but not sure whether it's the best allocation of my (scarce!) resources. Though on the flip side, apart from my phone, I haven't bought anything for myself above £30 for the past three years or so.
Agh.
