The tablet and app craze are catching up with business – this one of the main topics addressed at this week’s Citrix Synergy 2011 conference.  Even though the consumer level is getting t6he most attention, developers are also turning their eye towards the business segment. And, this week too, we’ve rounded up five of the most noteworthyiPad and Android apps out there:

iPad

Penultimate for iPad

Penultimate is the first app to make it on our list, and is a simple – yet extremely convenient handwriting app. The app lets users write and draw on the iPad’s touchscreen, thus extending to the functionality of the on-screen keyboard by allowing the creation of sketches, idea outlines and more.

MobileMe iDisk

Apple’s personal cloud storage service iDisk has picked up itself quite a bit of traction, and lets users access their files from their iPad as well as the rest of its mobile line-up. When logging in to the app, a list of the folders in one’s iDisk pops up, and user can select which one they want to view.

Desktop Connect

Antecea Inc.’s Desktop Connect remote desktop viewing app got pretty some good reviews from users, as well as reviewers including latimes.com. The app is the only one of its kind to discover all of the computers on a local network, and offers support for both VNC and Microsoft Remote Desktop as well as a number of other features.

Android

Locale

Locale proves to be one of the best solutions to a problem users have been trying to resolve: how to differentiate one’s personal life from their work tablet. Users can configure Locale to automatically changes device settings and carries out tasks based on time of day and GPS coordinates.

TripIt

TripIt can prove to be very effective for users on the go. The app will create a master itinerary out of travel confirmation emails forwarded to TripIt’s address, and also syncs with  your calendar and social networking sites as well as colleagues and e-mail.
