For the typical user running web/email/word processing/simple spreadsheets we have topped out on the processing power needed. Other than the ever increasing demands of Windows, most users are looking for smaller (and easier to carry), longer battery life, more rugged and with a constant net connection. Gamers and other people doing heavy CPU operations like authoring DVDs and big graphics still need the "big iron" and faster CPUs, but most others would be better served by smaller computers. It comes to the point where the human interface with a screen big enough to see and a keyboard big enough to type on are the limiting factor in practical computers size. (I consider an iPhone to be too small to do any real data input on).

I use my Windows Mobile based cell phone (a Samsung i760) for telecommunications, and since it runs Windows Mobile I can edit Word, Excel, PowerPoint, I can view PDFs, etc. With the Freedom Mini Bluetooth GPS all my Bluetooth devices (laptop, cell phone, etc) have highly accurate GPS at all times, too.

What makes my phone a slam-dunk tool (because the phone is always with me - it's my only phone number) is the Celio Redfly. Now I have a large screen, 90% sized keyboard, and 10+ hours run-time. It makes the Windows Mobile platform truly an alternative to a full-blown computer. In fact, I have a server on the Internet that I connect to remotely with my cell phone. I can run FEA simulations from anywhere I get cell phone reception, from my phone. My laptop rarely leaves the house any more - it's my phone and the tiny, lightweight, long-lasting Redfly.

Not to mention the Redfly is just the right size to be truly usable on an airplane - it's small enough that I don't have problems putting it on my tray, but big enough it's easy to read and type on. I turn the phone on, and leave it in my pocket, holster, or bag and just work on the Redfly (Bluetooth connectivity). Great accessory!
