Yet another article with no real information and just a bunch of fluff. Please, please stop wasting space on Toms Hardware with the gibberish from Barry Gerber.
In the words of Stewie Griffin, "Hey... shut up."
Honestly, if you didn't care for the last one, or the one before that, or the one before that, WHY THE **** did you open this one? Isn't that like the definition of insanity, repeating something you know won't work?
This is a tech community. All that should be required for us to have a discussion on a topic, such as "What is good or bad about UMPCs? Why all the negative press?" is just the question, which this article poses. Even if the article is short and lacking on data, it still is the seed of a discussion.
Moving on to the actual topic...
I think the UMPC idea is brilliant. It is hopefully what all portable computers will become. Tablet PCs are just a tad too large unless you really need a screen that size. Laptops in general can't be used while on the go or standing (and they shouldn't even be used on your lap a lot fo the time, because with some designs it blocks air vents or really heats up your lap). PDAs don't have the capacity to work as full-blown computers. Take the touch screen of a Tablet PC, combine it with a laptop-capacity hard drive, and try to make it closer to the size of a PDA rather than a Laptop.
Today, we don't have the technology that is needed to do it well. Finer resolution displays would be an asset, and hitting 1280x720 on the screen or going higher still would be great: images could be viewed without scrolling and text could be finely detailed for easier reading. Better batteries would also be needed so you could hit 8-10 hours, which is probably as much or more time using a portable device in a day than most people would like. Faster components would also be desirable, for media playback, multi-tasking, etc.
However, when you think about it, many things that are established standards today were initially attempted and done poorly. The first hard drive by IBM was a massive device that employed 50 platters, 24" in diameter each, with a yummy capacity of about 5 MB and a read speed of a handful of KB per second. Good thing people didn't cave in to a sentiment of "this is a slow, power-hungry, overly large piece of *@&$!" and stop working on hard drives.
