The folks at Frommer\u2019s, in partnership with Inkling Systems, Inc., did a superb job tailoring select Frommer\u2019s travel guidebooks to the iPad. But inherent limitations with Apple\u2019s tablet decrease the usefulness of Frommer\u2019s interactive travel guides.\n\tInkling developed iPad editions of Frommer\u2019s guidebooks for Alaska, California, Costa Rica, Great Britain, France, Japan and Spain. I downloaded and perused Frommer\u2019s California Day By Day, a $15 iPad version of the paperback travel guide that currently goes for $19.79 on Amazon.com.\n\tOne advantage the iPad Frommer\u2019s guides have over their dead-tree counterparts is immediately apparent: They\u2019re less expensive. They also have numerous additional benefits. The iPad guidebooks incorporate current weather information for destinations; enable you to view destination details, photos, and websites next to maps; offer excellent keyword search features that comb not only the book but also lets you search Wikipedia and Google from within the app; allow you to add notes and highlighting; and enable you to adjust the font size.\n\tThe gorgeous color photographs are perhaps the best thing about Frommer's \u00a0iPad versions. On Apple\u2019s tablet, particularly the new Retina-display iPad, the photographs are both stunning and wanderlust inducing. And you can view a variety of slideshows.\n\tSo what\u2019s not to love?\n\tWhile you can share the guide\u2019s content on social media, you\u2019ll need a Frommer\u2019s account to do so. What exactly is a Frommer\u2019s account? The California guide doesn't say. By searching Google, I discovered that you can only register for a Frommer\u2019s account \u201cduring the check out process of an online order.\u201d In other words, you must be a paying customer to have a Frommer\u2019s account. Bummer.\n\tI also found the California guide\u2019s travel advice to be mostly predictable and at times shallow. When reading about San Francisco, where I live, I found primarily the obvious tourist attractions mentioned. And in some cases, the guidebook paints a rosy picture of a destination that doesn\u2019t fully match reality. For instance, Haight Street in San Francisco \u201cstill kicks a pretty groovy street scene with throngs of fashionistas, punks, street musicians, and tourists trying to make sense of it all.\u201d The guide doesn't mention the street\u2019s particularly aggressive, and sometimes abusive, panhandlers.\n\tThe iPad itself also has a number of limitations as a travel guidebook replacement. Maybe it\u2019s just me, but I\u2019d rather not have a $600 piece of equipment in my backpack when navigating unfamiliar towns and cities. Aside from security concerns, the iPad adds weight and bulk to your bag. I\u2019d much prefer to carry print-outs of selected guidebook pages\u2014but the Frommer\u2019s app doesn\u2019t offer a way to print.\n\tThe iPad screen is also difficult to read in bright sunlight, so you may have a hard time viewing the guidebook\u2019s information when you need it most.\n\tUltimately, Frommer\u2019s iPad guidebook editions seem best suited for finding ideas about what to see and do before you go on vacation.
