I'd like to see rendering that looks good on all browsers, especially the BlackBerry browser, Opera Mini, and other phone browsers. You can download free
BlackBerry Device Simulators and then visit mini.opera.com on the simulator browser to install Opera Mini. In order for your BlackBerry Simulator(s) to be able to access the internet, make sure to download the BlackBerry Email and MDS Services Simulator Package from the same page.
I prefer pages that load and render quickly and are easy to navigate and that don't need javascript or flash to be running or even installed. Ideally, a client using the Lynx browser on a 486 with dialup should be able to book an appointment just as quickly as someone running the latest version of Internet Explorer on a computer with two quad-core QX9775 processors and a DRAM based SSD with an FiOS internet connection.
I'd also like for phpScheduleIt to work no matter what if any firewall or other software a client is running.
Oh, and I have not downloaded or tried it, but you can also get your iPhone emulator by downloading the
free iPhone SDK.
