Yep, I picked one up. I was going to go with the Supreme because it appeared better on paper at first, but honestly, looking around, it didn't seem like a good purchase even at $180. I didn't really want to spend $250 (sale) on the Galaxy S3 either at the time.
Anyway, the Desire 601 seems great so far. Nice and responsive. GPS locks on very quickly which is a huge improvement over my Motorolla Triumph. Also, I really think 4.5" is just the right size for a phone. I feel like the Galaxy S3 and other "phablets" are almost too big, which is probably why the iPhones stay in this range as well.
However, to my astonishment this phone doesn't have the hardware sensor for a compass. Even the cheapest phones have a compass. I'm not sure if this will affect anything, I'm just really surprised at the lack of such a basic feature.
Anyway, for $180 at the time, I think it was the best purchase.
EDIT: Price was $180 not $150. Corrected.
