A little while a go I tested running an OpenLaszlo DHTML application inside the Palm Pre SDK. The results were promising, but that was only the emulator running on my Macbook Pro. David Temkin told me that he has tested some OpenLaszlo apps on the Palm Pre device, and the performance was good. The Palm Pre has a powerful CPU, the ARM Cortex-A8, much more powerful than the older iPhone generations. The chipset is a 800 MHZ OMAP 34×0 by Texas Instruments:
The OMAP3440 processor offers increased performance and advanced multimedia benefits targeting applications that require high performance, such as the mobile Internet device (MID) market. The OMAP3440 applications processor brings full HD camcorder functionality to mobile devices, giving users the ability to record high-definition (HD) video, as well as enjoy new applications enabled by the large displays in the latest Smartphones and Mobile Internet Devices (MIDs). The OMAP3440 leverages TI’s high performance IVA 2+ multimedia accelerator to support 720p HD video record and playback, unleashing user creativity behind the lens. Additionally, at the heart of the OMAP3440 is a superscalar ARM® Cortex™-A8 that provides 800 MHz of performance to enhance applications that take advantage of the larger displays used in MIDs.
The processor performance – in combination with lightning-fast Webkit engine inside webOS – make the Palm Pre one of the few mobile device giving us the power to run DHTML OpenLaszlo applications with good performance – next to the iPhone 3GS. The 3GS is powered by the same CPU – using a different chipset. But Apple has decided to under-clock the CPU to save power on the 3Gs – utilizing only 600 Mhz instead of 833 Mhz possible.
OpenLaszlo DHTML and Flash for webOS
With the announcement of a first Flash 10 Beta for Palm Pre and Android in October 2009, Flash on mobile devices will experience a new era: for the first time it will be possible to run large Flash applications on mobile devices and phones with a good performance. The Nokia N95 – with Flash Lite 3.0 support – didn’t deliver the performance to run OpenLaszlo applications. With the new Flash 10 player for webOS it’s going to be a different game – and it’s a big chance for OpenLaszlo developers to build applications for webOS.
But with the Mojo SDK/Framework around, would you still build applications for webOS with OpenLaszlo? Yes, absolutely! If you want to skins your components, build web applications for iPhone and webOS, OpenLaszlo gives you Flash and DHTML runtime as a choice: Flash with the multimedia features for webOS and Palm Pre, and the DHTML runtime for iPhone Safari and Webkit in webOS.
