I really love those parenthetical titles! The software industry – and in fact anyone who wants to sell something – is driven by either addressing customer needs and wants, or trying to invent a need/want so that customers will buy a product.
Push email is a good example. Do you need it? Maybe. Does everyone need it? Probably not. Do you want it? Maybe. Do you need it because you want it, or because your job depends on you actually being able to respond to an email within one minute even when you’re taking a pit stop? That depends entirely on you and your boss. Or do you want it because someone says, “Push email is big!” [Incidentally, here’s an article about why Push Email may not be so great over at Modern Nomads that touches on the issue of want vs need.]
This post is about screen resolution. Screen resolution has gone up fairly steadily over the years. My parents’ first computer had a 15″ CRT monitor that cost $500 and could just barely handle displaying 1280×1024 resolution at eye-melting 60hz. Now, a 19″ CRT that can easily do the same at readable 85hz costs $90 from OfficeMAX. The 17″ LCD I’m using right now can easily support that resolution natively and cost about $200 – a similar one I just sold that I’d purchased in May of 2004 was $440. When my parents bought their first computer, the whopping 30″ Apple Cinema Display was completely unheard of as something a mortal could purchase, but now Dell has equivalently-sized displays that aren’t so crazy. Television screens used to be the size of a small toaster – today, even a college student can afford a plasma display (your college student may vary.)
We want bigger, we can have bigger, so we get bigger. What about PDAs? Instead of getting bigger, we want smaller. Witness the relative explosion of the Smartphone market as opposed to the palm-sized handhelds of various flavors. Smartphone devices are pretty cool any way you slice them – except for one thing.
The screen is really small! All Windows Mobile 5 Smartphones use ‘QVGA’ displays, 320×240 pixels. However, these phones don’t display any more data than the previous 176×220 displays – they just make it look prettier with more pixels. The same goes for VGA Pocket PCs, or high-resolution Palm-powered handhelds – a 640×480 Dell Axim X51V can’t display any more data on the screen than the 320×240 Axim X5 could, nor can my Treo 650 put anything more on its 320×320 screen than the original Palm could with its 160×160 screen.
It really is possible to cram more data on the screen – you just use a smaller font size. We get requests all the time – especially for ListPro – to add ‘high resolution’ support to our applications. The way I’ve seen this done, the screen font size is halved. My DateBk6 program on my Treo 650 can do this easily. The problem is… I can’t do it. I’m young, and even though I am nearly legally blind without my glasses, I can see pretty well with them on. That doesn’t make reading characters any easier when they’re as big as this period –> . [For a look at how this works out on ultra-portable and UMPCs, take a look at this blog post by JKOntherun]
We want smaller and bigger at the same time – smaller dimensions, higher resolutions. “QVGA is too small! It’s too ugly low-res!! Why would I want a Treo 700w when the screen is only 240×240! I want more pixels! More pixels! 10 megapixel cameras! XGA Pocket PCs!
Do people really need these tiny screens? Do people really want them? Are they being told they want them by marketing? Are they assuming that more pixels is better? Tech people aren’t immune to ‘more is better’ – I bought my new digital camera partly because it was just $20 more to get 7.1 instead of 6MP! Why get a regular value meal when you can biggie size it (disclaimer: biggie sizing no longer exists at Wendy’s) for just 40 cents more? Why get an Axim X51 (320×24) when you can get the X51V (640×480, four times as many pixels) for less than $100 more?
So what do we as a company do? Do we spend a lot of time adding a feature to our software just to make it more flexible, giving people the option to squint at their 2.5″ screen to see 300 lines of text instead of 150 (disclaimer: I made that number up.) Do we have to climb on that bandwagon in order to make sure we stay relevant? Or do we try to make software that is easily used on a 2.5″ screen by people with average fingers and average eyeballs?
I certainly don’t have the answer. I would love to be able to see more of my shopping list in ListPro on my Palm, but I don’t think I’d be happy trying to check off “Get eye exam” using my thumbnail when my nail’s thicker than the item I’m trying to poke on the screen. Maybe the ideal solution is a compromise – give people all their data when they want it, and readable data when they need it.
