Looking at what you get for your money Toshiba Qosmio G10 There is no doubt that laptops (or notebooks if you wish) have grown in popularity in recent times. We thought it time to have a closer look at what you get for your money these days. W e’re actually looking at two “fairly” similar computers in this review. When we say fairly similar, they’re both advanced laptops offering incredible features. The biggest difference is one is a “big brand name” at or near the top of the price pile; the other was sourced from a supermarket at a (much!) lower price tag. Once, not so long ago, laptop computers were significantly more expensive than desktop models and suffered badly in performance comparisons as well. They’re still more expensive – but now the margins are nothing like as wide – and the gap in performance has reduced to the point where for most users it doesn’t matter too much, if at all. Throw in the convenience factor of laptops and it’s small wonder they have become the computer of choice for a wide range of users – everyone from business people on the go to 8  Silicon Chip students replacing notebooks with . . . notebooks! At SILICON CHIP, when we review equipment such as computers, we’re not so much looking at degrees of performance; we’re more interested in the overall picture, what readers would be interested in, what you get for your money and how well the equipment works in the real world. We generally leave A-B-C comparison tests, particularly when it comes to PCs, to those who are best set up to conduct them. You can find such tests in any of the myriad of computer magazines available in Australia (both local and imported) – or you can also scan the ’net and find report after report. A word of caution on the latter: you need to read these reports carefully because you usually don’t know if the reviewer has a vested interest to report a certain way. The way some reviews read it would appear that there might siliconchip.com.au t Laptops: in 2005! Medion MD 95400 By Ross Tester be some consideration. Of course, there are also straightup-and-down reports on the ’net; just be picky and choosy what you read! Let’s explain where the impetus for this review came from. It was actually at one of the exhibitions we regularly visit (we try to keep abreast of technology!) that one of the sales people showed us their brand new computer with more bells and whistles than you could jump over. “Ho-hum”, I thought. “Another new computer”. I generally don’t get too excited over new models. Maybe they’re a bit faster, maybe they’re a bit cheaper. Maybe they’re more snazzy looking. Maybe they’re . . . But my ears pricked up when the salesman started talking about its major claim to fame: it used the “new” Microsoft Media Centre operating system. He demonstrated some of the capabilities of this new system (at the time it was so new he didn’t really undersiliconchip.com.au stand all it could do; it was mostly the usual salesman “gee whiz” factor). But what I did see intrigued me. Microsoft Media Centre is an integrated system which effectively turns your PC into a multimedia home entertainment centre. It can easily become the heart of a home theatre system or it can be used for personal entertainment. At the time, I’d read a little about Microsoft Media Centre and (wrongly, as it turned out) assumed that it was a product in its own right, available “off the shelf” like Microsoft’s other operating system offerings. So I called Microsoft’s PR agency and asked them for a review copy of the software. The very nice lady at the PR company explained that they couldn’t do what I wanted because Microsoft Media Centre only comes “pre installed” on selected (suitable) computers. “And by the way, its not actually called Microsoft Media Centre” (though that’s what it’s become know as) – “its corJune 2005  9 (Centrino) with 400MHz front-side bus and 2MB L2 EIST), 1024MB DDR Ram (2048MB maximum), a 160GB hard disk, a SuperMulti double layer DVDR-RW, an NVidia Geforce FX Go5700 video “card” and Harmon-Kardon integrated speakers (which, by the way, sound surprisingly good given their obvious size limitations). It comes with 802.11b/g wireless installed, along with Bluetooth, a V.92 modem and a 10/100 LAN (network) card. Sorry about keep referring these things to cards – force of habit – they’re almost always integrated on the mainboard these days – but you get the drift! One nice feature of the Wi-Fi is a switch on the side to easily disable it. Many machines require menu selection or a series of keystrokes to do this – and it’s so easy to forget. If you’re on a plane or in some other area where 2.4GHz wireless is a big no-no, just switch it off. Toshiba also call the Qosmio G10 “compact and portable”. Umm, sort of like a wheelbarrow full of bricks is compact and portable. With that huge screen it’s certainly not too compact. Yes, it is portable but at a weight of more than 4kg you wouldn’t want to lug it too far. The most striking feature of the Toshiba Qosmio G10 is that big, beautiful, clear With a machine like this, we believe screen. It’s a pleasure to work with.

The first thing that strikes you is that huge screen – a superb 17-inch WXGA (1440 x 900) CSV (a widescreen in TV-speak), capable of displaying 16:9 (widescreen) movies perfectly. And when you turn it on you notice just how good that screen is: big, bright and beautiful. (Toshiba claim to have special proprietary graphics chips built in to drive the screen. And it features two backlight tubes instead of the usual one). But computers need to be more than look good and have big screens, so we put the Toshiba to a variety of everyday tasks over the next couple of weeks until that inevitable phone call “We’re sending a courier to pick it up tomorrow . . .” OK, let’s lift the bonnet and have a look at what you get for your money. And it’s significant money, as we will discuss shortly. XP Media Centre edition helps you organise your movies, Toshiba describe it as “the ultimate digital entertainment photos, music etc and then either access them directly or hub”. In a nutshell, it is fitted with a 2.0GHz Pentium M via the remote control, or program them for later viewing. 10  Silicon Chip siliconchip.com.au One criticism you often see about Microsoft Media Centre is its inability handle digital TV. A pity, really: you get so much digital control in this machine but you can’t take advantage of digital television features! With a DVD player/writer/rewriter built in, you aren’t limited to the rubbish the TV channels are throwing at us lately. The TV tuner even has a remote control so couch potatoes need not worry . . . The DVD, incidentally, is a beauty: CD-R and –RW plus DVD-R, +R, -RW and +RW – and even dual layer DVD+R. One negative on the DVD is, like most brand-name DVDs, it is regioned. Personally, I find it offensive that manufacturers dare to tell me that I can only watch a pre-recorded DVD that they say I can watch – that is, one sold for region 4 (Australia/ NZ etc). Yes, you can change the region a limited number of times but once that number is up, you are stuck in that region. If you happen to be Not quite as large a screen on the Medion MD 95400 and you have to plug the TV receiver watching a region 1 (US) DVD in (that’s it on the side).
