iPad gets my job done in few occasion ,
1. Long hours in cafe / coffee shop, which in here I do not have to bring my charger , one shot go I can last 8 hours no problem.
2. On the bed reading and browsing Internet when the sleeping fails with the room light off. Reading has become such a pleasure.
3. Mobility on the go , all simple and basic Internet stuff can be done conveniently without using laptop , even walking I check mail , or finding information thru google.
4. Some casual gaming when I need it during bombing time , or waiting spouse when she is in front of the make up desk.
To me it's definitely worth to get an Ipad and reason I choose iPad rather than android tablet is because much more quality apps , standardized hardware so DEV can max out the iPad potential when developing app , which result in great app. Android will never be able to make this anyway. From 800 mhz processor to 1.4 ghz quad core, DEV have to make sure the app are balanced to all the device spec. Which resulted a undertuned app.
Currently only tablet serve me well is iPad , but hope other platform can catch up. I am sold when there is another tablet with 20 hours battery life + wide variety of quality app , no matter it's android iOS or window. LOL
* this new iPad retina screen is my main concern to upgrade from iPad 2. Really make a big difference especially reading and browsing web. Worth very cent IMO.
