I like iTap RDP to use to connect with remote desktops. My firm has virtual workspaces set up on our exchange server, and ITap RDP is the best way that I have found to access it. One change I would suggest making in the settings to ITap RDP is to use the pointer instead of tapping to click. The pointer is a bit more accurate,
Logmein is good choice for logging into specific computers. Very well designed and easy setup on macs and PCs.
Simplenote: I use Simplenote on my Mac (using JustNotes) and PC (using ResophNotes) as well as on my iPhone 4 and iPad 2 (using the Simplenote App). If find that this is a quick way to take notes, and syncs across all of my devices. I use the tagging function to organize everything, generally by subject area and client name. Much better than having stacks of yellow pads with my chicken scratch on them.
Reeder: I use this app to keep track of all of my rss feeds from Google Reader. This is a great way to keep track of all of your interests. I have groups set up to monitor blogs relating to tax, estate planning, Apple products, and Thailand.
Omnifocus: Simply the best todo list program I have ever used. Organized using the Getting Things Done philosophy, I love how when I am sitting at the phone, it will list out all of the calls I need to make.
Dropbox: A great file storage solution that works cross platform. Free. Best way to store your files.
AirPrint: this is built into the iPad, but unless you have an AirPrint compatible printer, then you will need software on either your Mac or PC. For Macs, I definitely suggest Printopia.
Evernote: I love this program because whenever I see an article, pdf or something that I want to keep, say a great news article on an area of tax law, then this program makes it so easy to retrieve and sort and keep. I subscribe to the premium, which is not expensive. Works cross platform. Allows you to email items to your account, and can be installed in browsers.
Fastcase, Black Law Dictionary (I love this for the Westlaw key number categories...a great way to search), Title 26 CFR and Title 26 USC, BNA Quicktax,
iCatcher: A great way to keep track of podcasts. There are many tax, estate planning, etc. podcasts, as well as some Apple related ones that I listen to.... Actually, I have a TomTom holder for my iPhone that goes into my car, and I plug it into my audio system. That way, I can listen to these podcasts while driving.
Docs2Go: My favorite editor for Microsoft Word on an iPad.
Keynote: Great way to present from an iPad. Don't forget to bring your adapters! If you touch the slide when you have the iPad plugged into a projector, then your audience will see a laser pointer like dot on the screen. Always seems to get some oooos and ahhhs....
Goodreader: great document viewer and organizer. Cheap.
iAnnotate: great PDF annotator.
PowerOne: Amazing calculator with many great downloads available.
To use Westlaw on an iPad, I do the following: 1) go into the settings on Westlaw, and turn off link viewer, 2) Download iCab mobile (a web browser) from the App Store and set it to desktop Safari. Use ICab to view Westlaw. For some reason the normal mobile safari doesn't work well. Remember to use two finger scrolling sometimes if the single finger doesn't work. When you want to email an article to yourself, be sure to select rtf (rich text format) as the .doc version used by Westlaw doesn't seem to work well with the iPad. These tips can save you from having to spend a lot of money on WestlawNext.
As stated above, sometimes you must use two fingers to scroll so that the entire page doesn't move.
Remember that if you have a web page you like, you can save it to your home screen. I have BNA Tax Management Portfolios saved this way.
Remember that you can do a google search not only across the internet, but also right on the page as well.
If you are trying to make folder out of Apps, the easiest way is to drag right up under the App, otherwise the App might move to either side, and it can be frustrating then to make a folder.
If you tap at the top of the screen, you can scroll right back to the top...works in mobile Safari and in emails.
Remember in iTunes to check the box to encrypt your backup (I got this tip on Daring Fireball, my favorite Apple site). By doing this, when you upgrade your iPad (or iPhone) software you won't have to reenter all of the passwords.
If you hold down some of the keys on the iPad, you will notice that some other characters pop up (such as a Section symbol, "§," if you hold down &).
