I had the Asus Eee Pad Transformer. That had two I think.
Great tablet, but I realised quite soon a tablet wasn't for me. I need to use programs like InDesign, and complex web pages like Drupal that a touchscreen is just too annoying to use.
So I sold it and stuck to my netbook and desktop!
This is why I don't particularly use my tablet all that much other than casual browsing/surfing and reading books in bed (as Kindle isn't backlit) aside from that it's still a gimmik.
The one thing it is really good at is using Adobes new set of apps (which are admittedly WIP) on android which allow me to prototype/wireframe websites/apps etc in minutes with the client. that's pretty cool.
i think the app market is going to implode and devices running them will feel like consoles rather than poots. I see the app market as a sticking plaster over the current problem of bandwidth and connectivity. With on line gaming starting to look so good, as soon as you get a good connection you will never think app again. First out of teh stable with a decent 4G will be a game changer.
its all about ease of access. The least easy access part about the fruitmakers fondleslab is its price.
It'll be shinier. And make you bend over more when you pay for it at the counter.
And i'll be there, bent over and ready.
As you all guessed.
Big change is rumoured to be the display maybe quadrupling the pixel count. Not that the current display is bad.
But sometimes just having a faster device shifts things. The improved speed on accessing emails stored in large mailboxes makes small savings on time regularly: multiplied across a year, it saved me loads of time and enabled me to have more data on board.
That meant i used it more, did stuff quicker and that brought a benefit to my business and my life. Some times a lot of little things add up to a hell of a lot.
There's less obsolescence on a tablet than a mobile as the inbuilt spec on an iPad one was pretty damn good. it's harder to make it hit the memory/speed wall compared to an old iphone.
iOS has to bring something gamechanging and processor thirsty to iPad3 to cripple/obsolete the original version.
USB isn't coming or a smart card slot. Unauthorised devices breaking the UI, routes to ping on malware.
TBH icloud/dropbox/etc gets your files on it/accesed on it easily if you know what you are doing so USB not a deal breaker. You cant USB to add functionality on: how many companies are going to write a driver for the iPad or be allowed to? Most accessories you want to plug in can communicate via WiFi or Bluetooth to the iPad (and a premium price charged to the end user to buy said device) so device manufacturers are going to cry too much about the lack of it easier.
New stuff comes along thats innovative to fill the holes. check this out for example.
