The Galaxy Alpha seems made for those who want a heftier version of a Galaxy phone, the 4oz phone sports a metal side gives it a more solid feel than the S5 and previous models.  On the other hand the USB, audio and and buttons on that band of metal are not waterproof unlike its siblings so there is a trade off.  The screen is a bit disappointing at 4.7" and 720×1280 resolution which is compounded by the lack of MHL A/V output from the USB port meaning you will need Chromecast or another solution to send A/V to an external device.  The price is very similar to the S5 and other competition, the features and lack thereof are what might drive your decision as it did The Registers recommendations here.  There is no word on its ability to bend as of yet.

"The Galaxy S3, S4 and S5 have all felt a bit too toy-like for their price tag. Technically impressive they may have been, but the build quality was, and is, too Fisher Price. The new Galaxy Alpha is Samsung’s counterpunch. It is a phone that tries to put aesthetics and build quality on an equal footing with the length of the specification sheet. Now who else does that? Oh yes."
