I'm wishing Apple would start to consolidate some of their iOS apps. There's a lot of similar/redundant functionality and in the spirit of keeping people focused on the content, it'd minimize bouncing around from app to app. Perhaps make some of them in-app purchase add-on modules. They'd each pack a bigger punch if:
Calendar = Calendars + Reminders
Notes = Notes + Stickies + Calculator or simple speadsheet column for running totals
iChat = FaceTime, FaceTime VOIP, Mail, Messages, Twitter
iBooks = iBooks + Newsstand + Catalogs
iPhoto = Pictures + iPhoto + Aperture Filters + a semi-intelligent online community gallery to replace instagram + Cards
iMusic = Music + Garageband + Podcasting
iMovie = Videos + Youtube + Netflix + Vimeo + [Picture in Picture option] + iMovie + Motion & Storyboarder
Remote = Remote, + Netflix/Hulu commands + Frontrow interface w/ Gestures... etc...
Prob need a quicker processor & a bit more ram tho.
