I still use my laptops more than anything. I use my iPad 4 for browsing all the time, and it's probably my favorite device for browsing without inputting anything major. I still use my laptops for writing, emailing, forums, and anything serious, because I find OS X Safari and Windows 8.1 Chrome/FF to be in general more reliable than mobile Safari/Chrome. If there was a good Bluetooth mechanical keyboard available for the iPad I'd probably end up doing most things on the iPad, but until that (unlikely) time I'll spend most of my time on full computers. I also probably split my gaming time evenly between the iPad (Xcom!) and my PC, with a little bit of gaming done on the rMBP.
