Some notes about my TabletPC

Here are some short comments both on the Toshiba Portégé M200 (as a piece of hardware) and on the TabletPC concept in general (software etc.). Note that these comments reflect nothing but my very personal opinion.

HW:

– Overall performance is nice (Pentium M 1.6 GHz, 768 MB RAM, GeForce FX Go5200 32 MB).

– The Geforce is sufficiently fast for playing low-resolution games (I’d say up to 1024×768 pixels) with rather poor texturing. It’s clearly not sufficient for playing current games with excessive use of textures (remember it only has 32 MB of memory).

– The keyboard layout is very unusual and plain stupid, particularly for CS/IT professionals (e.g. []{} are not indicated and placed wrongly, <> are in the wrong places, home/end are placed in the upper right corner, barely usable, windows keys are in the upper right corner too – silly). Grossly negligent.

– The lower part of the notebook (the keyboard) is a bit thick for my taste (coming from a thin, nice Sony Vaio N505X). Typing is tedious and bad for the wrists. [update 20040617: Meanwhile, I’ve managed to get accustomed to it]

– The screen is disappointing. It’s a high-res screen with 1400×1050 pixels. That’s nice. It’s bright and I can even read it in sunny environments. That’s nice too. The bad thing is the very low contrast and the distortion which is probably caused by the special screen coating (makes the screen feel rough to improve the “paper feeling” when writing on the screen using the pen). The distortion drives me crazy and my eyes start burning after a very short time (this never happened with any other LCD screen I’ve used so far). I’ve tested it both with and without glasses. It’s always bad, but particularly harmful for people wearing glasses. Be warned! [update 20040617: Meanwhile, I’ve managed to get accustomed to it]

– The touchpad is a bit too small (and therefore inaccurate) for a 1400×1050 screen resolution

– The rest of the HW (as far as tested) meets my expectations (= is okay)

The thing I’m asking myself: Why is it so hard to build an ergonomically good convertible TabletPC or notebook device?

SW:

– Pen input recognition is pretty amazing from a programer’s perspective (that’s perhaps where all the “wows” come from) but clearly disappointing and insufficient from a real-world user’s view. It’s slow (if you decrease the delay the recognition rate drops rapidly). The input recognition rate is (for my hand-writing, which isn’t neither particularly nice nor ugly) correct in about 95% of the letters. This rate drops to about 30% when entering URLs, mixed character/number words, special characters and in mixed, multi-language environments (which might be seldom in the US, but very common for us Europeans and particularly Swiss people). It’s totally unusable for entering passwords and such. Some of the problems are probably due to missing learning/adjustment capabilities (MS obviously chose a dictionary based approach instead). [20040617: this is no longer true for XP SP2 RC2 (Lonestar) where handwriting recognition and overall ergonomics are much better]

– Pen input requires too many clicks and is a painful experience overall. Lonestar allegedly will address some of the issues, but as far as I can judge from the video cap, it still won’t do a decent job (pen input is still too complicated and inconvenient for being an alternative to keyboard input). After using Windows XP TabletPC Edition for a while I have to conclude, that this is basically just a regular Windows XP with an “Inking” add-on. It’s not really designed for tablet use and pen input (even in Lonestar, you can’t just start writing inside a text field – that’s how it should be done actually). Clicking on regular Windows icons is as difficult as choosing the right menu entry. Both are too difficult and not very handy. I wonder how Apple or Palm would approach such a task.

– Windows XP TabletPC Edition has a nasty bug that prevented me from calibrating speech recognition (it displayed little squares instead of a readable font)

– When entering user credentials at the login screen, people can observe (thanks to the virtual keyboard displayed on the screen) when shift is being pressed. That’s a potential security weakness.

– For me, the use of the pen can be reduced to painting and designing (therefore, it’s pretty handy, much more convenient than using a regular mouse)

farewell suse, welcome debian ;)

when upgrading suse 9.0 to suse 9.1 yesterday early morning, my workstation’s setup got screwed. it wasn’t suse’s fault (one of the cdroms was bad) but nevertheless i had to cancel a party due this unexpected incident (it was my only working desktop linux setup and therefore mission critical for my diploma thesis). as i couldn’t solve the problems, i decided to switch to debian instead (currently “testing”, will upgrade to “unstable” asap). so far, a rather positive experience. debian boots faster, debian shuts down faster and even kde 3.2 runs faster on it (despite of lacking pre-linking!). for installing it, i’ve used the new debian sarge netinst beta4 installer. had still some flaws (e.g. screen resolution was not set correctly, dns settings had to be fixed manually, keyboard settings weren’t correct), but overall, it’s surprisingly stable already.

nb. i still think that suse is doing a great job as a distro (very convenient to use and well integrated). but now as i switched to debian for my desktop, i’ll probably install debian on my tabletpc too, thus standardizing on debian and windows xp for workstations and gentoo for servers.

good news: finally, my toshiba portégé m200 has arrived at the ssd-shop :) i’ll pick it up tomorrow. i’ll use the opportunity to also order a logitech mx510 optical mouse, a lite-on 431 sx slim dvd +/- burner (external, usb 2.0) and a replacement battery for an old vaio.

[update 20040512: ssd’s supplier didn’t have the mx510 on stock, so i decided to buy it elsewhere (i need it now, not in 2 months ;).. unfortunately it’s sold out already in the only shop in zurich where i’ve seen it a couple of days ago. no surprise for me (hey, it’s the ultimate gamer mouse :), but obviously for logitech and partners. i’ve made a reservation so i’ll get it asap.
further i decided to order the lite-on 431 sx slim dvd +/- burner (external, usb 2.0) at fuerst-informatik.ch, who offered it for a really good price with (as i was told) quick delivery. further, as i’ve surprisingly noticed that my portégé m200 features 802.11b/g (not only b), i will also order a new wlan access point: linksys wrt54gs which can be equipped with embedded linux: Linux on the WRT54G, LinksysWrt54g – SeattleWireless:)]

Technical/business English

Recently, Christian gave an interesting talk how to write correct technical/business English. I hope I can adopt the rules he mentioned, both for my technical writing in papers and in this weblog. Concerning this weblog, I should most importantly try to avoid any expressions that might be perceived as rude, offensive or in any other way inappropriate. This probably isn’t as easy as it sounds as different cultures perceive things differently.

The slides of Christian’s presentation are available on request only (Send him an e-mail message). As a good starting point, he also recommends reading “The Elements of Style” by William Strunk, Jr. which appears to be a classic. Another good web resource: The following Wiki entry.

ergonomically nice mice

currently i’m looking for a mouse with good usability/ergonomics and control. two promising candidates i’ve found so far:

logitech mx510 performance optical mouse (800 dpi/cpi, 5.8 mpixels/s data rate, up to 15g acceleration) (the u.s. model is red as opposed to the european model which is blue)
reviews: hardware pacers, geekextreme, extremetech, gaming nexus. brand new. should offer excellent control (it’s targeted towards hc gamers ;). eventually remove the removable little weight element [picture]

razor viper optical (1000 dpi/cpi, ?? mpixels/s, ?? g)
reviews: ex hardware, tom’s hardware. brand new. razor is renown for gamer gear. probably best control but not very handy for everyday use as it lacks back and forward buttons and other nice features the mx510 offers.

as i don’t intend to use the mouse exclusively for gaming purposes (i mostly use simulators, not fps) i’ll probably go for the logitech mx510 performance optical mouse due to its features (has more buttons).. looking forward to test-driving it :)

btw. it’s a pity that manufacturers don’t offer any truly smoothly scrolling mice.. and last but not least: i don’t like wireless mice for a number of reasons..
