Proud owner of a Yellow 1520.3 since August of 2014.
I will say yes,
1520 is the best Windows Phone of all time. Now some astute readers might have seen me in the sister thread in the Alcatel Idol 4S forum proclaiming
that phone as the new best all-around champ. So let me clarify a little.
I think there is definitely a division.
Windows Phone sits in the middle (meaning WP 7 up to WP 8.1) with
Windows on Mobile (begun as CE to 6.5 and starting back again with W10M) bookending either side. As we all know there are several
contiguous versions that are not
continuous.
When it comes to the 1520 it towers over the Windows Phone 8 (+Black) and 8.1 (+Denim) landscape like the colossus it is. RJ
has it right. The many strengths of this phone have made it legendary and justly so.
I had my 1520.3 on W10M for a time, but I came to my senses and reverted it to 8.1 and retired it to
camera and travel companion duty (translate, maps/nav, music and video for passenger entertainment...).
This device just shines on Windows Phone 8.1. I'm not sure it holds up as well under W10M or will continue to be as relevant under the new return to Windows on Mobile. The times have moved beyond the 1520.3, as is only right with tech. The 1520 remains a highly important bookmark in the journey and is unsurpassed, IMHO, as a Windows Phone from the days when market share was actually visible and had reached double digits in several countries.
