I'm actually writing this post from my new (new to me...got on eBay for a little under $500, will have to pay another $60 for a new battery that's maybe 1.25x the size of an iPhone) Toshiba R100 ultraportable. It has become my main computer. I'm a college student and having a two-and-a-half pound, .65" thick, 12.1" screen laptop just makes sense for when I want do go out to my classes and take notes, surf the web etc. No processor-intensive stuff to do really, o the machine's 1 GHz Pentium M squeaks by as being acceptable for what I use it for.
This weekend I have the choice of using this laptop (which has no optical drive, which I don't really miss t tell you the truth on a portable machine...laptop optical drives are just copromises between performance and portability anyway), my Del Inspiron e1505 or a loaner Macbook 1st gen from the campus bookstore, for my regular work. The Macbook is a fun little machine, however I think I'd find myself running Windows on it for most of the weekend and not really using it as it's placed awkwardly in between my 12.1" 4:3 Toshiba and my 15.4" 16:10 Dell. So I'll probably end up using either the Dell (at-desk work, hooked up to webcam, mic, headphones, USB devices, external monitor) or the Toshiba (web and email and documents because it has a decent keyboard, plus remote into the Dell). I don't need a 13.3" laptop with spinning 2.5" media when I have a 15.4" laptop that does that and a 12.1" ultraportable that eschews an optical drive for portability. It does have an SD card slot though which I'm really happy about...and no, it uses a regular (1.8" I think) hard drive however I'm thinking seriously of switching it over to a 32GB SSD.
But I digress. I'd say most of the student market, if presented with a durable, small screen (12.1" would be ideal, either wide or normal aspect ratio), thin ultraportable that would be fast due to inclusion of an SSD (ULV processors aren't an option for speed gains right now...fastest one is the Core Solo at 1.33GHz) and enough memory (mine has 1.25GB, its max), you would get a TON of sales. No need for an optical drive if you're going to leave that at the dorm when at lectures, no need for a fast processor to listen to music, surf the web, edit documents, that sorta thing. Just thin and light is all we need...and trust me, I've gotten tons of comments about my laptop because it is really tailored for this type of environment if you think about it, as long as you have another computer when you need it.
To continue the discussion about optical drives, and then screens, the last time I used an optical drive was to try and rip some CDs. The CDs ripped slowly and I could've downloaded the audio files online faster than the CDs ripped. Before that, it has probably been a month or two, again for ripping CDs. Before that, a few months previous, burning sme CDs. The sort of thing I would be doing on a larger machine, not an ultraportable. I'm fine with downloading (legally) my music and either network-sending files, sending them via flash srive, or waiting till I get home to fire up my (heavy) optical drive to burn some media. In a 2-3 pound ultraportable, I see no reason to include an optical drive.
For screen size, I agree that there is some such thing as too small. However my Portege is the result of the Foleo being cancelled, and that was with a 10.4" widescreen. Then again the resolution on that screen was just 1024x600 so not quite so hard on the eyes as you might think. After the Foleo was cancelled I tried getting the Sharp Actius MM10. 10.4" screen, regular aspect ratio, XGA. I ended up with a 12.1" 1024x768 display and am happy with it. It's plenty big enough for what I use it for and if I need bigger I just close my laptop, plug it in to an external setup and go for it!
On the topic of widescreens, I dunno but I found myself squinting at the Macbook's 13.3" 1280x800 widescreen. Then again I'm laughably nearsighted but I have no complaints whatsoever about my 12.1" screen. I might have some about a 1280x800 12.1" widescreen. then again I could be convinced otherwise...
What would get me to go Mac on this note?
1. Durable construction (aluminum sounds great, right now my R100 is plastic and magnesium and it holds up fine so far)
2. SSD-based with the latest ULV processors (I want lots and lots of battery life, but understand that you can really only fit a 3-cell battery into these things, but I also would like performance if it can be had, and with SSDs it can definately be had!)
3. No optical drive to keep thickness at or below 0.8" inch (my current ultralite is .65" but I'll budge a little bit if the specs merit it) and weight below 3 pounds, preferably well below 3 pounds
4. Regular hardware and software structure that is open (e.g. Mac OS X on an Intel platform with an SSD that is upgradeable, same with memory and maybe even processor if possible). I don't want to have to hack my ultralite to get functionality I need (Foleo wouldn't have been so bad but some of these ultralite platforms).
5. Decent price ($1000 or less, preferably $800 or less, even better would be $700 or less since you're not really giving much in the way of components for an ultralite...well, except for the SSD).
Again, I have now dismissed the Macbook as too "all things to all people" and want something specially built for my needs: a flyweight that throws its weight around.Yes, I'm now ultralight-spoiled but I'll bet Apple could sell a metric buttload of these to students for which the Macbook even is a little big for carrying around to class and such, particularly in light of the ultraportable bunch!
