This app is actually quite responsive! I'm surprised there's not as much lag as I was expecting. Here are some
complaints I have, which I bet they're working on:
1. Printing. For med school, I have to open up PowerPoint presentations and print them out 6 slides per page, and the formatting never comes out right when using Keynote, so I HAVE to use MS Office, which I hate installing on my Mac. Unfortunately, onlive desktop (obviously) can't print any documents. This can be solved on their end by adding printing over internet support or by adding native iOS printing support.
2. Accessing documents. Getting files into the onlive desktop is a kludge that involves uploading the files to their desktop via their website from a Mac or PC. If I'm out and about with just my iPad, it's obviously silly to require me to go home to my Mac to upload files that I want to work on. This can be solved by adding Dropbox support.
3. Accessing a web browser. There's no access to a web browser, which is totally understandable considering that's the upside of paying for the $10/month plan. But again, that makes it a pain to actually get documents into the the onlive desktop since most of the documents that I need to edit are located on my school's website, so having a web browser to download the documents first would solve this problem.
4. Native keyboard. The app doesn't make use of the iPad's native keyboard. I am actually very surprised by how well Windows 7’s keyboard works! But it's still be nice to use the iPad's native keyboard. This is something that I'm sure Onlive could add in an app update. (by the way, the stylus support is much better than I had expected too!)
What makes this really interesting is that they plan on making a Mac client too, so theoretically you could pay $10/month and have access to Windows and Office in the cloud, where you can keep your office documents with zero syncing whatsoever (since for each session you're accessing the same persistent desktop). Very nice proposition for someone like me who doesn't want to run bootcamp on my 64GB MacBook Air (it would take up too much space). I can take my iPad to school, work on a document there, and then open the app on my Mac too (inside a window) when I get home and continue my work.
I feel like this is exactly where Windows needs to be for me personally:
just another app on my iPad's home screen!
