Could you elaborate on this? My experience has been mostly positive with all of the things you mentioned, so I'd like to hear what it is that you feel is so bad about it. The web browser is simple, but fast and does what I need it to. Podcasts are easy to subscribe to, download automatically, etc. Not that any of that is anything special, but it is enough to make it completely acceptable in my eyes.
This has been elaborated on in other posts in other threads, but just as a recap:
1) Podcasting downloading is very spotty; sometimes podcast episodes won't automatically download and sometimes don't even show up in the app catalog, even though they've been published and are available using other apps/OSes. This includes even some of the most high-profile podcasts (e.g., This American Life). Additionally, for podcast sources that keep an archive of all episodes, WP8 will attempt to download old episodes in order to fill its subscription settings, even if the old episodes have been marked as already played.
2) With regard to media playback (including podcasts and audiobooks), WP8 lacks playback speed control. WP8 also inserts audio gaps into albums that are meant to be gapless (live albums, orchestral/classical music, electronica, Dark Side of the Moon, etc.). (For what it's worth, the old Zune music players supported gapless playback, but it never worked very well in practice). Additionally, WP8 loses playback position when switching between media (or a host of other triggers), which kills audiobook playback. Playlist/library management is also effectively non-existent since the loss of the Zune software.
3) IE10/Trident is exceedingly slow at rendering/resizing pages (and the various skins, such as UC Browser, do not rectify this), cannot load pages in background tabs (and often must reload tab contents upon switching tabs), and is unable to maintain visible text boxes/form fields in a wide variety of situations.
This is core functionality for a smartphone/media device in 2013 (or even 2008), but Microsoft has dropped the ball.
