I just would like to add ... As much as I love my iPad ... And it's what I am typing on now .... I still find a laptop and my desktop very useful ... And love those things too
For web surfing .. Checking messages ... Watching you tube ... Playing on Facebook and the coffeehouse ... The iPad is portable and easy and fun
Everything else I own is PC ... My DAW and laptop ... And those are my work horses when things get serious
Although I found garage band in ipad to work in a pinch when song writting with a friend a few weeks ago .... And irig and the irig midi are just hands down TITS.....in terms of an amp sim and a portable sythn box for any keyboard equipped with midi
Well anyway
My answer is still iPad
But laptops and desktops still are more important to me
I Guess that's my conclusion to my thesis
