From fine automobiles to designer handbags, we've covered various companies that let consumers rent expensive objects instead of buying them. The latest to join the herd is New York-based Rent the Runway, which allows women to rent designer dresses.

Dress-seeking fashionistas browse RTR's collection and schedule a delivery date (next-day delivery is available, as well as same-day in New York City). RTR then sends them the dress, including a second, back-up size to make sure the fit is as good as the design. Rental costs are around 10% of a garment's retail price, and range from USD 50–200. Customers can rent for four or eight days, after which they return the dress in the USPS return envelope that RTR provides. The extra size—which RTR provides at no extra cost—must be returned unworn.

Further proof that its founders have thought through the concept from a consumer's point of view, RTR also lets members rent a second style for just USD 25. Which gives them a back-up option for last-minute decisions, or a second dress to wear at an elaborate wedding or a multi-day event. Brands currently on offer include Just Cavalli, Helmut Lang, Proenza Schouler and Hervé Leger.

Appealing both to consumers who are cutting back for economic reasons, and to those who value experiences over ownership (dubbed transumers by our sister-site trendwatching.com), there's plenty of room for concepts like Rent the Runway to grow, especially if they provide their clients with heightened convenience as well as heightened style.

If Twitter can be used to track packages, publish school menus and crowdfund startups, why not help tackle the US healthcare crisis too? Cell phones are already changing the way healthcare is delivered in the developing world, after all, and now Twitter promises to transform the delivery of healthcare information for stateside consumers.

ASKch is a new service from Nashville-based healthcare information provider Change:Healthcare that allows users to send quick healthcare questions via Twitter and have them answered within 60 seconds. Consumers can simply tweet a question such as, “what is diabetes” to @askch, which is now in beta; in return, they get a short description of the disease and a link to more information. Those seeking prescription pricing information in a particular ZIP code area, on the other hand, can tweet “cost of celebrex near 37209,” prompting the service to tweet back, “average price of $163 in 37209″ in return. Questions must be formatted according to predefined types, which currently include: what is (health issue); what is (drug name); cost of (drug name) near (zipcode); generic for (drug name); and generic discounts for (drug name) near (zipcode). Over time, however, Change:Healthcare plans to expand those possibilities.

The new application is just the first phase of what will ultimately be a much larger service from Change:Healthcare that aims to help consumers "be more informed and potentially save hundreds, if not thousands, of dollars," the company says. Where else could Twitter be used to answer consumers' standard questions quickly and in real time...? (Related: In-home STD tests with results by text message.)

Orggit offers a new take on web-based information storage. We've already seen this service in a several guises: from ultra-secure 'memory' storage inside a Swiss mountain, to an online locker for loved ones to open after the user's death. Orggit's unique selling point is the In Case of Emergency (ICE) card that it supplies with every subscription. Using the card, medical personnel can call a dedicated helpline and quote the member's ID code to gain access to all of their medical vitals, which could be a lifesaver. In case of a lost wallet, the good samaritan who finds it can also call the helpline and Orggit will arrange an owner-wallet reunion.

Orggit is essentially a consumer-friendly rebranding of parent company Morgan Street Document Systems' core service, which it has operated for high-end clients since 2003. As the online information storage industry goes mainstream, Orggit is aiming to appeal to the masses by offering them a comprehensive and highly-organised place to store critical data. In addition to medical records, there's a wallet section for storing card and ID data, an 'accounts and codes' area and a virtual filing cabinet that can hold about 10,000 documents. A free Orggit iPhone app—rapidly becoming a web start-up essential—gives users mobile access.

Annual subscription to Orggit's service costs USD 49.99. This includes the ability to add up to 10 users and manage access rights for each user. While consumers are overwhelmed with places to store data online for free (email providers, Google Docs etc.), Orggit's core value is in the structure and security it provides. The ICE card gives further peace of mind to users. One to localize for other languages and regions?

Offering a professional alternative to working from the nearest Starbucks, a new service from iStopOver makes it easy for people to rent (very) short-term business space worldwide. Created by Canadian tech enterprise Brightspark, the website provides a fully-automated service that connects offices with office-needers. Listing is free for hosts, while guests are charged a 6–11% service fee.

Rental terms can range anywhere from a few hours to several months, with spaces for rent including warehouses, boardrooms, offices, desks—even parking spaces. Users can refine their search according to particular requirements, such as wifi access, phone systems, catering, etc. (The service was launched two months ago, so available properties are still limited.) Guests and hosts can communicate through the site to exchange details. The booking process is automated, and iStopOver handles all payments online, only releasing payment to the host when they enter a reservation code given to them by the guest on arrival. This acts as a security measure for guests, giving them the option to leave without revealing their reservation code if the workspace doesn't match up to its description. The benefits? Those without offices gain access to a suitable working environment and professional image, while hosts can make money from empty spaces.

iStopOver for Office Rentals is an expansion of iStopOver's original home rental model. Both share features with services we've covered before on Springwise, but iStopOver looks to be growing into a one-stop solution for short-term rentals. One to partner with regionally?

Seat Geek is a free service that helps users find tickets when they're cheapest. Currently focused on Major League Baseball games and select concerts in the US, Seat Geek employs a sophisticated algorithm to predict whether the price of a queried ticket is set to rise or fall—similar to what Bing Travel (formerly Farecast) does for flight tickets. If the price is expected to go down, users can sign up to receive a free email alert when it's at rock bottom. Seat Geek also scours the web in for the best deals at any moment, linking to affiliated ticket merchants like StubHub, RazorGator and eBay.

Seat Geek's patent-pending algorithm draws on a large pool of data that includes millions of historical ticket transactions. This data is crunched together with other factors, such as, for baseball games: team statistics, the weather, the venue, the price-level of the seat—even who'll be pitching. According to SeatGeek co-founder Jack Groetzinger, the algorithm is accurate 80% of the time, and it's also self-training, meaning it gets better every day.

As our sister-site explains in its latest briefing, consumers increasingly expect instant gratification. Seat Geek and other 'prediction engines' take that one step further, by drawing on the web's informational riches to tell consumers how things will be, enabling them to make better decisions now. The future has never been as near, and opportunities abound for entrepreneurs that can bring it even closer.
