The Kendo UI NumericTextBox hides the decimal portion of its value when focus is in the control and when the decimal part is zero. For example a value of 1,345.00 will appear as 1345 when the focus is put in the control. If the decimal part is non-zero then the value is shown. From a usability viewpoint the disappearing zeros is inconsistent and can be misleading/confusing to a user who may not realize that they can enter a decimal part. So I think it would be valuable for the control to always show the decimal part of the value.
When I enter the following entry in numeric text box "1k" should populate "1000" "1m" should populate "1000000" "1g" should populate "1000000000"
When users see a field where they're expected to enter a dollar amount, a lot of people intuitively try to type something like "$45.30". However, since the shift key is forbidden, they get "445.30". I suggest allowing users to type in a single, superfluous dollar sign as the first character in a CurrencyTextBox, and then ignoring it during form submit.
For cases where validation after the fact isn't good enough there should be an option that disallows setting numeric textboxes to null. If the user sets it to null and moves to another field the textbox should reset to 0.
Please focus on adding flexibility to the numerictextbox. I'm jumping through hoops to get a field with a displayed percentage of 75.75% to appear the same way in edit mode. I understand the need to keep the control reasonably rigid, but I would hope additional customization options could be add. I gave up and am doing everything in a custom editor/ input text box.
It is better if kendo numeric textbox formats value (comma will be added after 3 decimals) as user types, especially for currency values. There are so many jQuery plugins available in market to achieve this. Kendo Numeric text box is not working as expected when integrate with these plugins.

I know it's not officially supported, but when you use it in hybrid mode in an iOS UIWebView, the events sometimes seems to get mixed up. Then when you clic on a filed, it jumps to the the next one while flashing the keyboard. It doesn't happen always, but just clicking in a few fields on a form and it starts. We had to rollback using it in our codebase. I have a video of the behavior and the code (based on your mobile sample).
