Retronym's has updated Tabletop with some cool new features.
• CloudSeeder - access the Tabletop Community
• Audio Copy - collaborate with other Apps!
• Module Bundles - great discounts!
I haven't bothered to reinstall this, so I'm not sure how great those discounts are... their iTunes page indicates that basic instruments still run between $6-$10.
SoundCloud CloudSeeder support is nice, and AudioCopy is always a welcomed addition, but all of my previous criticisms remain. It really needs some kind of sequencer/piano-roll for the non-step-sequenced instruments and CoreMIDI. To be fair, a lot of people seem to enjoy this app, You can certainly make some music without buying the In-App Purchases, and it is a very pretty app.
Tabletop is still free, so at least you don't have to pay $15 to find out you need to pay another $45 for most of the functionality... as all of their early customers had to find out the hard-way.
Update: Telengard checked out the bundle deals and posted about it in the comments section here. It seems like you can unlock everything for $25, but it will lower that price if you have already purchased instruments. Make sure you have "restored purchases" on the iPad you're trying to do this from though, in order for the corrected price to display.
