We just submitted iPad version of MobileNoter to App Store. Hopefully it will pass review process and will be available on the iPad grand opening.
iPad version is capable of working with two modes, Cloud and Wi-Fi. This is single application. And there is no 5Mb limit on a page. MobileNoter for iPhone 1.3 (that also have these new features) will be released very soon.
We had to cut off some features in the iPad app to be able to submit it by March 27th (which is requirement by Apple to be in App Store in the day of iPad sale start). Particularly, there is no encryption support (SSL is there) and passcode lock. We will finish porting these soon and will submit updated version. Also, this version can be unstable in some conditions because we do not have a real device yet, it was developed using iPad simulator.
And now some screenshots:
