I am getting ready to purchase my first iPad. I want to use it to replace my netbook mainly for travel. The plan is to use my wireless keyboard and therefore be able to create documents using Pages and simple spreadsheets using Numbers (which I am new at - Excel/Word user). I also want to use it to blog on my travels. Using a screen keyboard will not work for me for large amounts of typing. On the flip side, I want to be able to use it as a "tablet" and surf the internet, get emails, photo, apps, etc. How doable is my idea and would you recommend iPad Air or iPad mini? Thank you so much!
