I've read so many threads on the subject that I thought I'd just post my own. I have managed to completely replace my laptop with my iPad. I recently took in on a 2 week business trip and did not need my MacBook laptop once. To clarify: I purchased my iPad as a novelty item hoping that it would replace my MacBook but figuring that it wouldn't. I use it for mostly business purposes but also for personal things. Please ALSO note that it is NOT a replacement for a full computer like an iMac. As you will read in point 1, I purchased an app that allows me to log into an iMac remotely. Here are the apps that I got that have replaced my MacBook: 1) RDM+ (or similar app): This app allows you to remotely log into your always-connected, always-on desktop/laptop computer back at home. Meaning, you can log in and access accounting data, photoshop, etc. NOTE: pretty slow (2 - 3 second lag time) over 3G, only about 1 second lag on wifi. 2) Pages & Numbers: These actually work great. I have no complaints and they replace my Excel and Word on the MacBook. The spreadsheets are similar to those of Excel and Word (or Numbers and Pages) on a Macbook/iMac. Note that not all functions work exactly right- sometimes some images don't transfer properly and formatting can get screwy. But for the most part they actually work great. I have not tried Keynote but suppose that it works in the same manner. 3) CoPilot HD: fully functional, voice turn-by-turn guidance GPS system (for the 3G iPad only) with spoken street names. $30. Unbelievable! 4) Netflix: why not enjoy some of your instant queue Netflix while on the go. I use it all the time. 5) iDisk: I use MobileMe for email and cloud data storage. Their newly upgraded app was worth the wait. You can store data right to it and open it on your iPad, as well as open it in different programs like Pages and Numbers. 6) Skype: makes your 3G iPad a big phone, if you are so inclined, and have the SkypeOut plan (I do). You can't do 7) FTPOnTheGo: if you do any website work, including programming or HTML coding, etc, this is the perfect app for you. Access any website on the go and make changes wherever you are. Well designed app. 8) QuickSale: my wife uses this. Basic accounting / invoicing program allowing you to create invoices and email them right from the app. Pretty neat for $10. There are hundreds more that can be used to basically eliminate the MacBook. I also know that some of you will go out there, buy it, and then post here and say "I couldn't make it do that blah blah blah...", well if you notice the post, it says how I made my iPad...meaning MY iPad, not yours. These are just some helpful suggestions for those of you in limbo! So, hope it helps!!
