If you're a Twitter user with iPad, maybe you've been waiting for this for a long time. Twitter just released the official Twitter for iPad app and it's remarkable.

The new app interface is a series of panes that can be expanded and retracted, opened easily without the need to click on any fiddly buttons. Simple navigation options down the left of the app allow you to flick between your timeline, mentions, DMs, lists or searches. and the brilliant "slide to refresh" feature you'll probably already know and love from Twitter for iPhone app (now it's universal, runs on both iPad and iPhone).

The size of the iPad screen means you can read articles, or view photos and videos while still keeping the rest of the app's functions in view, there're some neat touches that allow you to view information quickly. When you click on a link in a tweet, the internal browser slides in from the right to display the article, photo or video. Also, if a tweet uses a hashtag, then clicking on it will bring up that tweet and others underneath that use the same tag. Follower suggestions are another useful feature. If you select a user's profile it suggests similar users to follow further down the page, that is a good way to find interesting people to follow. Also, there are several ways you can follow tweeted conversations: using a two-fingered drag, you can take a peek at the chain of messages. If you just tap on a tweet and it's a response to another tweet, you'll see the chain of messages in a full pane.

Now let's start a new tweet. As shown in the screenshot below, you'd be surprised how much you'll appreciate large, readable text. The text entry field looks like a notepad, which is an apt metaphor for writing on the iPad. Also on the text entry field are buttons for attaching photos from your iPad photo library, tweeting your present location, or shrinking URLs.

The settings for the app are rather simple, which I also find to be refreshing. Other than adding or editing accounts, there are two other buttons: Services and Advanced. Services lets you set up your image service, video service and read later service (Instapaper or Read It Later). Advanced has buttons for setting image quality, show hashtags in trends, enabling TextExpander, and turning sound effects on and off. There's also a button for installing a Safari bookmarklet - tapping it directs you to Safari, where you're given directions on how to set up the bookmarklet.

This new Twitter app makes it much easier to read tweets, get at the content contained within, and to see user's details and the flow of conversations. However, there are a few minor glitches that need to be addressed. The internal browser is slow to open a linked article, although it’s smooth once opened. It can also be harder than it should be to close exposed panes when sliding them back to the right. Sometimes they get “stuck” midway, requiring an extra slide to get them off the screen. Anyway, it's really nice to see Twitter team and Loren Brichter have carried on Tweetie's legacy of UI innovation with Twitter for iPad. Great job guys!

You’ve seen Twitter clients like TweetDeck or Seesmic, but you’ve never seen one like this. You’ve seen news readers like NewsGator, Google Reader, or, even, newer ones for iPad like Pulse, but you’ve never seen one like this. You’ve seen news aggregators like Techmeme, Google News, Skygrid, Yahoo News, Hacker News, or Huffington Post, but you’ve never seen one like this.

This is how Robert Scoble described for the new "killer app" on the iPad which is hot trending and making big waves on the internet today - Flipboard. The world's first social magazine that brings to life the stories, photos, news and updates being shared across Twitter and Facebook. It turns your account into something that looks like a magazine, also you can build a custom magazine which means you can turn every single person you follow into Flipboard, including lists. It will turn that into a beautiful magazine-like interface that is easier to read than any other reader. Switch on Facebook you’ll see your friend's status messages, articles, photos and videos, all laid out like a newspaper in a way you’ve never seen it before. Click on any item and you can see the originating status message and all comments, also you can "like" the item or comment on it.

iPad is here, not a tablet computer, not a netbook. It starts at $499, the price is a lot better than what I thought it would be, and we know what the Apple iPad does do. such as: iBooks, Games,10-hr battery life, Wi-Fi, 3G, green tech etc. Apple says "It's the best way to experience the web, email, photos, and videos." But I have an iPhone and I have a Macbook Pro. I’m not feeling a huge need to have an iPad. I have to say I'm kinda disappointed and confused in the iPad.

Here's what I don't like about it:

• Huge Ugly. It seems like a bigger iPhone or iPod Touch. Grrrr
• The A4 chip seems like a bad idea. No way Apple is going to consistently be better than Intel or AMD at making low power chips.
• No camera. which means no video conferencing and no quick shots for posting. Please! even the new iPod Nano has one!
• 16, 32, or 64GB is all you get, because there’s lack of an SD card reader built directly into the iPad.
• You won’t be able to plug in an external USB keyboard or/and a digital camera you already own without buying a separate USB adapter.
• Only runs apps from the App Store. Want to run a different browser on your iPad? Too bad.
• No Flash for now, bad enough on the iPhone. maybe Apple is hoping that HTML5 will take off quickly and start to disintermediate Flash as the primary technology powering video playback on the web?
• Perhaps the biggest disappointment is, No multitasking! saying I can't listening to Last.fm radio while reading my email? I can't have Twitter client open at the same time as my browser? No, thanks!
• It uses microSIMs that literally no one else uses, then it doesn't support China Unicom 3G.
• Basically it works the same as the iPhone. I want a 10-inch iPhone running Mac OS X, not this big iPod Touch.
• The Name iPad. Apple should have watched this MadTV spoof "Apple iPad" from 2007 first. LOL

Here’s the problem with all this. That’s not to say the iPad won’t sell, or that I don’t want one. I don't think Apple will have any trouble selling these things. Some people say Apple is Evil that Apple plans for the iPhone OS to be the future of its product line. Because the iPhone OS is designed for Apple’s total control, not only does the hardware have to be flawless, the software must be too. and the only way to ensure that is to have Apple approve every inch of it. You can say it's a closed platform, you can say that App store may not be open, but third-party development will extend the iPad to do things we can’t even dream up, just give it 6 months and we'll see.
