Last year, we talked about...

• Desktop / Embedded convergence

• Focussed on the embedded ports of Qt:– Embedded Linux (previously existing)– Windows CE (recently released in Qt 4.4)

This year, we’ll talk about...

• Desktop / Embedded / Mobile / Web convergence

• Mobile activities:– Symbian and Maemo 5 ports– Qt Mobility project– Nokia

• Web activities:– QtWebKit improvements– Web Runtime

Why should I consider this?

• Huge installed base

• Economies of scale

• Blurring definition of devices

• Leveraging the Web

• And because it’s easy with Qt

PC addressable market

• Market still growing but decelerating– CAGR 2003-2008: 14.5% 2008-2013: 5.2%

• Portable trend– Notebooks and laptops overtook in 2008

PC market by Operating System

• Market fairly established:– Windows clearly dominates– Mac OS X rising in popularity– Linux making slow inroads

• Low-cost, public sector, etc.

• Many toolkit options:– Microsoft has several offerings– Apple has only one official offering– Linux has two alternatives (one of them being Qt)

Mobile addressable market

• Overall market: greater volume, but slower growth:– CAGR 2007-2013: 2.9%

• Smartphone market: similar size, huge growth:– CAGR 2007-2013: 27.2%

Mobile market by Operating System

• Smartphone market very fragmented:– Symbian will remain the leader for the time being

– Fragmentation will increase before it decreases

• Each OS has its own toolkit

The Embedded market

• Varied processors and OS, but changing

• Consolidating:– Processors: ARM and MIPS– OS: Linux (mid and high-end)

• Hardware seriously underpowered:– Little or no graphics acceleration– Memory limitations

What is convergence?

• “Technological convergence is the tendency for

different technological systems to evolve towards

performing similar tasks.”– Wikipedia - http://en.wikipedia.org/wiki/Technological_convergence

• The lines of separation blur:– Different devices do the same jobs

– Consumers start expecting the same behaviour

• Example:– Web browsing

14

14

Devices themselves are converging

• CPU, GPU and battery life are very close:– Laptops are becoming lighter– Netbooks are getting better battery life

• Example: Nokia 3G Booklet has 12 hours

– Mobile devices are getting more powerful:• Example: Nokia N900 mobile computer

• Services are the differentiation

Device convergence: 3-device illustration

Smartphone Mobile Computer

Nokia N900

ARM 400 MHz processor 256 MB of RAM

32 GB of storage

Netbook Asus eeePC

Atom 1.6 GHz processor 1 GB of RAM

80 GB of storage

Laptop Dell XPS

Core 2 Duo 1.6 GHz processor 2 GB of RAM

160 GB of storage

16

16

The Web is also forcing convergence

• Zero install, zero deployment

• Emerging Web technologies:– HTML 5 / CSS 3– Web widgets– Web tools

• Easy access to developers– Large pool of talent to tap onto

17

17

Note of warning: web isn’t so simple

• Many standards, poor support:– HTML 4, HTML 5, XHTML 1.x, CSS 2, CSS 3, ECMAScript

– Browser engines must cope with broken source code

– Web developers must cope with engine limitations

• Desktop landscape:– Internet Explorer 6 still over 60%

– IT corporations block upgrades

• WebKit dominates mobile:– Used by Nokia, Apple, Google, Palm, Research in Motion¹

– Existing 3rd-party browsers for Windows Mobile

1) Blackberry doesn’t use WebKit yet, but it’s expected to do so soon

Without Qt, you’d use...

• Desktop:– Windows: Microsoft .NET framework– Mac: Apple’s Cocoa framework

• Mobile / Embedded:– Symbian: Symbian C++ API– Windows Mobile: Microsoft .NET embedded

• Web:– HTML 5 / CSS 3 / custom JavaScript extensions– Adobe Flash, Microsoft Silverlight

Desktop with Qt

• Traditional Qt segment– Strongest API base– Most customers

• Platforms supported:– Windows 2000, XP, Vista, 7 (and some Server)– Mac OS X 10.4, 10.5, and 10.6:

• 32- and 64-bit, PowerPC and x86

– Linux with X11• Any platform

21

21

Embedded and Mobile with Qt

• Renovated focus for Qt:– API completeness – Qt Mobility project– Performance, memory profiling

• Platforms supported:– Linux with DirectFB, on ARM, MIPS, and x86– Linux with X11, on ARM and x86– Windows CE 5.0, 6.0, Mobile 6.0, 6.5– Symbian 3.1, 3.2, 5.0 (and future versions)

22

22

Using Qt, you have...

• One code base for all platforms – Minor tweaks depending on form factor

• Powerful UI capabilities– Animation Framework, QML– New UI editor (Project “Bauhaus”)– OpenGL, OpenGL ES and OpenVG

• Web integration:– QtWebKit API
