Homesharing is AMAZING
Interface has kinks, but OK
Not being able to drag unbought iTunes store songs to playlist, ULTIMATE FAIL!

In my original response to this post I totally agreed (and then some) with the sentiment, but today I stumbled upon a not very dressed-up but completely functional way to get previews to playlists the same as before. Go to the home page of the iTunes store, scroll all the way to the bottom and look under Features, click on Browse, it brings up the store in a horizontally split panel like the original itunes browser, then you can click on genre, subgenre, it loads the artists, you can pick one and it brings the albums and tracks into the lower pane of the window in list format so you can preview -- and buy-- songs from there or drag them into a playlist in your own library if you want that.
Minor hitches: there seems no way to back up from clicking on a genre (no All at top of the store list), and if you try to use the search from this browsed view of the store, it does the search but reverts to the new itunes format for presentation of the results. Well, it's better than nothing. I am happier now than when I thought I could not drag previews into a playlist. My playlists are my new "shopping cart" I guess. I'll just move the buy button column all the way to the right so I don't click on any buttons prematurely.
Another thing I am not too happy about: it doesn't seem like there's anyway to throw a track into a wishlist from the new format in the store. You can only wish-list albums? Of course once you go back to the wish-list, you can preview and buy tracks from it but the wish "list" isn't really a list, just a place to stash references to albums, so it doesn't let you store (or for that matter delete) single tracks. Well this is another reason to use browser format in the store and drag such single tracks into a playlist, which becomes your own version of a wishlist the same as before.
UPDATE: well using the store's browser (under features at bottom of store page) and its old list format is a little tricky since there's no All in the main genre column, and you can't use search without the results presentation reverting to the new itunes store format. To stay in the browser mode, you need to know the genre of the earliest release of that artist that the itunes store offers. That's the genre you click on for the "genre" column. Then click on All in the subgenre column. Then let it load the artists and then when you type a few letters of the artist's name in the artist column, or scroll to it, the store's browser will bring up all the albums available and you can click on the one(s) you want to load into the lower pane, so you can drag preview tracks into a playlist on your own drive from there (and buy everything later from that playlist after you're done shopping around).
Man. The album I wanted to get preview tracks for was in "dance" genre but the stupid browser wouldn't load anything for that artist because their first release into iTunes store was categorized as "rock" genre. Finally I stumbled onto this by going back to the artist page in the new format and looking at the genres of all their albums and trying them separately in the browser until "rock" worked and then I realized I had to use the genre of the earliest release in order to get the browser to spring for showing me any works by that artist. Duh, who knew, who cared what genre some other album was back in 2000.
Wow. I really hope iTunes will refine the current options for the new formats in the store. It's not that I hate them. It's that they are not as useful as they could and should be. We should be able to choose between the current format (pops up that box with tracklist and lets you one-click to buy) and some button that flips into list mode so you can preview tracks and drag them to playlists on your drive if you want. Especially since the new format doesn't give you a way to wish-list just certain tracks.
