The fact that we have to buy "apps" to do things we can already do with our PC/Mac computers is sort of annoying. I mean, I can go online and edit my Google Docs for free, but not with my iPhone or my iPad.*
That said, I bought an iPad and ended up selling it on eBay. However, I will probably buy v2. I own a 3GS, and will be selling it to get the iPhone 4. Still, there are some things I wish I could do for free, without shelling out 5 to 10 bucks for an app. Maybe as the platform becomes more capable, we will see that change.*
Same goes with games. Farmville is an example. You can play for free on facebook, but have to PAY for an app to do the same thing on iOS. Poker, too. Any of those Zynga apps!
