A few thoughts after having spent a week with WP8 and the Lumia 521:
Pros:
+The WP8 layout/style is appealing
+Responsiveness is solid (especially compared to Android devices)
+Idle/low-use battery life is great
+Nokia Music offers a good selection of free streaming music and is ad-free (!)
+Nice physical construction
+Simple, expandable storage
+Live tiles bring the best elements of widgets into a sane format
Meh:
=Screen is mediocre (IPS is good, but resolution and viewing angles are merely tolerable/sufficient with poor contrast/black levels)
Cons:
-App support is extremely lacking (and free apps are generally ad-riddled)
-Internet Explorer/UC Browser can't handle large/multiple web pages, and Opera Mini isn't available
-Music/podcasting support (no gapless playback, regardless of app; built-in podcast support is weak; playlist support needs to improve)
-Lack of Google services/support, even for Internet Explorer
-Scrolling vertically through the homescreen to get to apps/live tiles is cumbersome
-Active/moderate usage drains battery fast
-There's a dedicated Bing button
Overall: At the moment I'm using the Lumia 521 primarily for media playback (while at the gym or on the go) and as a quick-reference second screen, and it's mostly fine for those purposes (with the caveats listed above). It's a huge step down from iOS in terms of apps, though -- not only are games right out, but banking apps, hobby/website apps, GMail, Pulse, Opera Mini and the like are also unavailable and the closest equivalents/workarounds are also a significant downgrade. I'm still happier with the 521 than I've been with any Android phone/tablet I've owned/tried, though, and may very well make it my main phone/portable device if supplemented with a tablet (next iPad Mini/future Windows 8 device).
Wishlist: I'd love for Microsoft to offer some better app organization (faster access to apps that aren't at the top of the start screen), a better core media app (gapless playback, simplified design, sane podcast management), and switch the search button back to fast, context-sensitive searches (with a long-press for full Bing) in WP8.1.
What I'd love even more on low-end devices is better memory usage (particularly by IE/Trident). It's shocking how bad this is on WP8. My wife's iPhone 4S (also with 512 MB of RAM) can handle pretty much any webpage I throw at it, whereas I ran some tests yesterday on the Lumia 521 that show just how bad Microsoft's memory management/web browser is:
1. iPhone 4S with background updates enabled, multiple apps "open", music streaming, seven heavy websites open in seven tabs in Safari -- loads and the Pulse webapp with no problems (except scrolling on the login screen doesn't scroll the popup properly); also no problems loading the Pulse standalone newsreader, browsing stories and multitasking back and forth.
2. Lumia 521 with background updates/live tiles disabled, all apps (including start screen) closed, Fuse newsreader launched (with half the feeds of Pulse on iOS) -- Fuse consistently crashes when attempting to display the Bad Machinery webcomic.
3. Lumia 521 on fresh boot, background updates/live tiles disabled, all apps closed, IE used to open Pulse webapp -- crashes when browsing multiple stories (or when loading aforementioned webcomic).
4. Lumia 521, background updates/live tiles disabled, locally stored music playing via Music + Videos app, UC browser used to open three mobile forum tabs (m.neogaf.com) -- music app automatically closed, only one tab actually loads content while other two display out of memory errors.
Honestly, as bad as Android is with regards to Chrome and memory, WP is not [that much/at all?] better -- I'd imagine that even the 3GS (with 256 MB of RAM) would run circles around the 520/521/620/625/720 and all the other 512 MB WP8 devices.
To be fair, though, if Opera Mini was available, that would probably shut me up on the IE/memory bit.
