What can my smartphone not do?

I’ve blogged about how the Apple iPhone can’t do this and can’t do that. Here, I'll talk about what my smartphone, the HTC Desire, can't do.

To up the ante, I'm not going to compare the HTC Desire to the iPhone. Doing so wouldn't be fair to the Apple fanboys. I'm going to put my smartphone up against a computer running a desktop OS (desktop, notebook, or netbook running Windows, Linux, or OSX).

Here are the things the HTC Desire can't do when compared to a full PC.

• I can't buy movie tickets online at The Grand Cinema website. I can buy tickets at every other Hong Kong cinema site except that one. None of the other smartphone platforms can do so either.
• There's no optical drive so I can't access optical media.
• Even if I have DVD files, I can't play them because I'm not aware of a DVD player software for Android. The DVD files would first have to be encoded. This brings me to the next item...
• I can't encode video on my HTC Desire. First, there's no encoding software for Android. Second, I can't rip source files from a DVD. Third, CPU is not fast enough. My quadcore desktop CPU that clocks in at 2.5ghz still needs about 40 minutes to convert a movie. Several years ago, my Pentium 3 that ran at 1Ghz took about 6 hours to convert a movie. I don't want to imagine how long a mobile 1Ghz processor would take.
• I can't plug in USB devices (ie, flash memory drives, peripherals, etc).
• I can't perform elaborate photo editing. I can still do basic things like resize, rotate, and crop. I can even edit things like brightness, contrast, and saturation. But I can't do layers, extracting, etc.

That's all. That's the best I can come up with. The first item is the only really disappointing one. The others are things that you wouldn't ever expect a mobile device to do anyway. Can anyone else come up with some more things?

By the way, there are a couple of things that my smartphone can do that surprises even me.

• Edit and create PowerPoint presentation. Even the official Microsoft version of PowerPoint on Windows Mobile was view-only. However, I can only edit text. I can't insert images and I can't even edit the slides' styling.
• Access the full desktop-version of my HSBC online-banking web site. The iPhone browser can't do it. I couldn't do it even if I spoofed the browser-agent in Windows Mobile. This means, I can pay bills, transfer funds, and manage my investments while being nowhere near a computer, bank branch, or ATM.
• Play Flash-based web games. I'm not talking about simple stuff. I'm talking about games like Bejeweled and Plants vs Zombies.
