I am sure this has been discussed quite a few times on this forum and I have used the search button but cant seem to find what I am looking for. I am looking for apps to possibly replace my laptop (MacBook Pro Mid 2012). Its running just fine and I am going to keep it but I really think my iPad 3 could do everything I need. My iPad must be able to do these task: *Use Track Changes and ability to view comments (Can Pages do this?) * View PowerPoints (I already have Keynote) *Surf the Web (Mercury and Safari do this great) *Print to AirPrint Printer (I have an HP Envy 110 and it works nicely) I already have Keynote and just need Numbers and Pages. I have pdfPROvider for PDF annotating. In my usage, could the iPad replace my laptop?
