Wow, that is almost all I can say (I guess I better say more, otherwise this will be a very short post, but let me repeat: wow). Future plc today (and last night) just launched 54 magazine apps that are designed to be part of the new Newsstand feature found in iOS 5.
It would make my fingers hurt to list all the magazines, but they are easy enough to find simply by searching "Future plc" in the App Store.
Clearly these apps had been embargoed for release today. All the apps are universal so it will be interesting to see if these apps are simply replica editions, or whether they employ native tablet designs.
Subscriptions prices seem to vary from magazine to magazine: Mac|Life, for instance, is charging $5.99 for individual issues, or $0.99 per issue when you subscribe; Guitar World's subscription prices are $7.99 for an individual issue (ouch), or $1.99 per month or $14.99 per year if one subscribes.
By the way, a pretty funny line is included in the app descriptions by Future: Note: This digital edition is not printable and does not include the covermount items or supplements you would find with printed copies.
