Some quick [unscientific] observations:
The M4's fast; consumes lots of power; the screen rocks more than a traditional laptop screen; the fan is much louder than the ThinkPad T42 (I was plugged in which causes the M4 to default to high-power); and I am not yet comfortable with the keyboard.
Keyboard observations: I've owned almost a dozen ThinkPads over the past decade, and I've been spoiled by the wonderful ThinkPad keyboard. The M4 keyboard is not bad mind you, but I'm not adjusting to it very quickly. Here are a few differences that I've encountered today: When using the Accupoint (TrackPoint, for you IBMers) the left and right mouse buttons are now top and bottom mouse buttons. Now Idea why Toshiba did that. I'm constantly clicking on the wrong button. In addition, the Accupoint seems very stiff to move around, even after adjusting the settings. The ThinkPad Keyboard has CRTL & ALT keys on each side of the space-bar. The Tecra's layout is very different. My productivity has dropped, largely because I have 10 years of ThinkPad keyboard experience to undo. Again, this is not a bad thing, but it will take some getting used to. Of course, I'll soon be doing everything in ink, right?
Screen observations: I 'm beginning to understand why wide angle viewing is such a big deal for a Tablet PC. When I look at the M4 straight on or use it in laptop mode, the screen is fine. If I'm even a few degrees off center, however, the screen readability drops. This would not be a problem with a laptop but a tablet, as I'm finding, is used very differently. For example, I tried to show Kathy a video clip. She was sitting next to me on the couch and could not see it. If I want to sit in a chair and lay the tablet on the table in front of me, it's difficult to see. If I prop it up a little, it's fine. If I want to write with the tablet in my lap I have to make sure that I'm looking at the M4 straight on to get the clarity that I would expect. Unfortunately, I have no way to compare this screen to another tablet, such as the Fujitsu, so I don't know if this is state-of-the-art or if I'm justified in expecting more.
As I type this, my fan has kicked into high gear. It does that from time to time. For the most part, I've been able to manage the power settings, but there's a high pitched whine - probably like my blog. I'll see what I can do to mitigate that and share what I've learned. On the topic of sharing, I have a list of questions people have asked me on or off the blog. I'll collect these and respond soon. Thanks for your patience.
I realize that not everything I've shared about my quest to become YABHTU is positive. I don't like to complain, but I'm not going to sugar-coat something that I think could be better either. As for the comments that I have made (or will make) about the Tecra M4, you should know the standard of comparison that I'm using. It's the IBM ThinkPad T42p. I've been fortunate to have this laptop for almost a year, and it's a delight. For the most part, I've been spoiled by IBM, the ThinkPad and the service and support. Oops; That's not entirely true. There was the one time I tried to give IBM $50,000 and they would not take it. But that's another story.
I guess this is all a part of the learning curve. I work with many new systems each year, and I retain few. Of those, still fewer do I recommend to clients. I'm still a long way away from any definitive conclusion on the tablet platform. I want to give it a fair chance.
All in all, my Tablet PC experiment continues well, though I'm not sure I did the Tablet PC justice in my impromptu demonstrations to David and Jason. My demonstration of OneNote and MindManager were not as smooth as I would have liked. Still, I think I was able to make a compelling argument for why I think the Tablet PC is a platform to watch. David's comment was that he's glad that he "pays me to evaluate hardware and software to figure out what works and what does not." There's still much that I want to learn about the Tablet PC as a paradigm for getting things done.
As I learn more I'll share it here. Over the next few days, I'll try to switch and do the bulk of my work in Tablet mode and see what kind of an impact that makes on my productivity.
Enough rambling. It's late.
As always, a special thanks to those of you who have taken the time to post comments with advice and recommendations.
