Below are some screenshots running on the emulator for the Mac.

By twisting one’s hands appropriately on either side of the phone, objects could be rotated in place. Pages could be panned and scrolled by moving a hand up and down, and Microsoft also proved that text could be entered and edited on the main screen through a stylus while the other hand scrolled the page — a movement that would be akin to the motions a user’s hands would make if he or she were writing on a sheet of paper.

A quick motion toward the device could also be interpreted as a “click,” according to Microsoft.

Bottom line?  Jott wins on features, Zenbe wins with their easier to use interface. 
I’m still using both for now to see which one wins after extended use. 

Jott

http://jott.com
So this app is more for note taking, but also operates nicely
as a to-do list.  What makes Jott different is that it has a voice
recorder, which records locally, then uploads to the online service for
transcription.  The transcription then appears in your list as text,
and can also be played back as audio.  I really like the speed and
convenience of entering things while walking down the street.  The paid
version of Jott will create calendar entries and send emails. 

- voice recording and transcription
- automatic syncing
- good online app, web version, and mini desktop app available (Adobe Air framework)
- customizable bottom icon set for quick access to lists (limit 4 visible at once)
- sorted by date entered, or a simple “priority!” flag, no other options.
- can move items from list to list on both iphone and web
- sharing with others, and integration with 3rd party email and calendar programs (paid upgrade)

Issues:
- Since this is a slightly different animal, it is somewhat unfair to
compare the features to dedicated to-do lists, but I will anyway since
that’s how I use it.  I miss the ability to reorder things.
- This is more of a bug, but recorded items will randomly stay in the pending state only on the phone, but appear transcribed online (using
2G iphone firmware 2.1).
- The web version is feature rich, but a little clunky when editing or moving items.
- On the iphone, you mark items complete by very deliberately swiping your finger, which animates a strikethrough of the text.  I found this hard to do while walking down the street, the slight angle of my  swipe would scroll the page instead.  A simple checkbox is easier to use.
- Completed items stay in their original order, adding visual noise when scanning the list.  You can ‘clean up’ all items at once or delete each one individually, but this becomes repetitive.  The web version allows sorting by ‘done’ all at once.

Zenbe Lists

http://lists.zenbe.com/
Zenbe is an email aggregator, but also has a nice, free simple iphone to-do list app.  The to-do application is really elegant to use and the web version is the best I’ve used so far.  It also supports sharing with others.  That is a feature I have not tested.

- auto sync on launch with manual sync button
- drag n’ drop reordering within lists on the iphone and across all lists on the web version
- sharing lists with others
- due dates

Issues
- You can only move items from list to list on the web version.  I’ve found myself accidentally entering a bunch of items in the wrong list and then unable to put them into the right place until I got to the computer.

EasyTask

http://www.easytaskmanager.net/
Summary:
- Getting Things Done format, with project and context views
- nice dashboard with today’s tasks, next 7 days, etc.
- online sync (manual), but the web version seems mainly for viewing, not task entry
- saves completed items, but does not support reuse or undo if accidentally marked complete
- Tasks ordered by date, no other sort options
- can move items from list to list on phone only

Issues:
- When you drill into a project and add a new task, the form is blank, forcing you to re-select the project instead of defaulting to the one you just selected.
- Being GTD oriented, it helps if you follow a strict David Allen methodology. Although I like the ‘tagging’ aspect of GTD theory, I am not so strict with my categorization and date sequencing, so I find the extra steps of selecting a project, context, and due date, a bit more cumbersome.  This app is most useful if you enter due dates for everything, a step I often disregard for items that are dependent upon previous steps.
- When entering tasks, there is an enter key on the keypad which is useless since it doesn’t support multiple lines of text.  It’d be nice if that enter key said ’save’ or ‘done’.

DoBot

http://dobot.us/
- Nice and simple. 
- Supports, dates, priority, and big notes
- Sorting options
- Ability to hide old task for later reuse (essential for grocery lists)

Issues:
There is an interaction disconnect here - the ‘done’ trigger button should always be in the same location, however it is in the upper right for entering notes, dates, priority, and saving the whole task, but is
inexplicably in the bottom right of the keypad when you are entering the task title.  It requires 2 steps - on opposite sides of the screen.  I still find myself constantly tapping the blue, but slightly grey-out ’save’button several times before correctly typing ‘done’.

FYI, I sent an email letting them know about this and they responded saying this would be addressed in the next version.

To Do

from AustinBull Software - Demo: http://www.austinbull.com/

Thank you for the demo.  You just saved me money.  I have not used this app, but from the demo, it looks like an interaction nightmare.  This app does not follow any of the typical iphone conventions or style, nor simple Fitt’s Law proximity heuristics.  It isn’t internally consistent either; click the title text (?) to save in one place and a button in a different place…  And it assumes you will always want to add notes to a task, adding the extra step.  Yikes.

And at the time of this post, Toodledo, Nozbe, and Remember The Milk only had a web app, so they were not considered.

Enable pipelining
Browsers are normally very polite, sending a request to a server then waiting for a response before continuing. Pipelining is a more aggressive technique that lets them send multiple requests before any responses are received, often reducing page download times.

To enable it, type about:config in the address bar, double-click network.http.pipelining and network.http.proxy.pipelining so their values are set to true, then double-click network.http.pipelining.maxrequests and set this to 8.

Keep in mind that some servers don’t support pipelining, though, and if you regularly visit a lot of these then the tweak can actually reduce performance. Set network.http.pipelining and network.http.proxy.pipelining to false again if you have any problems.

Render quickly
Large, complex web pages can take a while to download. Firefox doesn’t want to keep you waiting, so by default will display what it’s received so far every 0.12 seconds (the “content notify interval”). While this helps the browser feel snappy, frequent redraws increase the total page load time, so a longer content notify interval will improve performance.

Type about:config and press [Enter], then right-click (Apple users ctrl-click) somewhere in the window and select New > Integer. Type content.notify.interval as your preference name, click OK, enter [250000] and click OK again [default is 120000, this quote=500000, another site uses 750000]. Right-click again in the window and select New > Boolean. This time create a value called content.notify.ontimer and set it to True to finish the job.

Increase the cache size
As you browse the web so Firefox stores site images and scripts in a local memory cache, where they can be speedily retrieved if you revisit the same page. If you have plenty of RAM (2 GB of more), leave Firefox running all the time and regularly return to pages then you can improve performance by increasing this cache size.

Type about:config and press [Enter], then right-click anywhere in the window and select New > Integer. Type browser.cache.memory.capacity, click OK, enter 65536 and click OK, then restart your browser to get the new, larger cache.
