Trials of the Sony UX90: Comparisons to the OQO 01+
One of my favorite side computers has become the Sony UX90 that I keep with me as a backup machine.* Although it runs Windows (which I've written about in less than positive terms many times before), I have tried to keep things simple: install only the basics. I have NewsGator, Outlook (from the Microsoft Office Suite - also installed), Skype, Trillian, Gizmo and, of course, PuTTY. I didn't try to replace my main work machine, a MacBook Pro, and really don't expect to be able to accomplish the same types of things.
The wireless reception on the device is great and the built-in utility does a good job of searching for networks. It also has a bit more straight-forward configurability for prioritizing networks than Windows Wireless Zero Configuration utility. (In all honesty, though, I usually prefer Windows WZC because some manufacturer's configuration utilities are poorly thought out.)
All of the problems I had with the OQO are taken care of on the UX. My biggest complaint with the OQO, however, had to do with the battery and things are not much better with the UX90. I thought it was inexcusable that the device lasted, at best, 2 1/2 hours with light wireless usage and general surfing. The UX90 will average just over three hours under the same type of usage dynamics. I solved that problem with both machines by buying an extended battery. The OQO now lasts upwards of 4 1/2 hours and the UX90 lasts often more than five hours. This type of poor power "longevity" is still inexcusable in an Ultra Portable, in my opinion. The benefit of such a small device really is it's ability to be used throughout the day. If you can't rely upon that, you lose the "ultra" part of Ultra Portable because you need to carry a bunch of batteries everywhere you go. I want to be able to use a UMPC the same way I use my cell phone (rather, PDA phone) - use all day and charge at night. Or, if I'm lucky and my PDA phone has a low power wifi chip, I can get close to two days of use out of it.
Having had two different types of UMPC'esque (Ultra Mobile PC) devices has taught me an important lesson in input. A full or, at least, mini style keyboard is really needed to do anything of consequence. A thumb-board simply doesn't cut it. In the case of a Blackberry or PDA cell phone like the Treo or Nokia E61, a thumb-board works to a better extent because of how small the device is to begin with. You can comfortably [learn] to hold the phone with both hands and type decent responses without much stress. With both the OQO and UX90, the problem of holding the device comfortably is exacerbated by the fact that the device is too heavy to use similar to the way one would use the a PDA. So, while enjoying our latest vacation, there were times I really wished I had a Stowaway bluetooth portable keyboard or access to something like my Thinkpad X40. The fact is that even with the added weight of the Stowaway keyboard, the UX90/Stowaway combination would be more convenient than carrying another true notebook with. The worst part of input is when you need to use a lot of odd characters like "/" "|" "=", etc. One of the items that hooked me on OS X six years ago was all of the standard Unix utilities underneath the GUI - and simple program additions like the Terminal. When you don't have access to your normal "environment" (i.e. my desktop and list of programs I frequently use), you learn which ones are the most important. For me, I spend much more time at the Terminal than I realized. So, that fact made trying to use the UX90's thumb-board somewhat inconvenient (of course, in a pinch, I was happy to at least have that).
One item that puts the UX90 far ahead of the OQO is the screen. I ran into more problems with the weird resolution of the OQO and dialogue boxes not fitting in the screen vertically. This meant that when installing program xyz, one has to guess what is below the taskbar. Even if you put the taskbar in auto-hide mode, it doesn't solve The only trouble I had was reading the screen in direct sunlight. The coating of the screen is highly reflective and makes beach reading somewhat amusing: you need to tip the screen away from you in order to view the display so as to see through the glare from the sun.
The UX90 is really what the OQO should have been. The device runs much cooler than the OQO and also handles applications faster. I know we're not comparing like processors and the Core series of processors weren't available from Intel when the OQO came out, but considering the Transmeta Crusoe processor was touted for low power, small devices, it's performance on the power and heat side make it non-ideal in practice. I haven't personally owned any other Crusoe based devices, but if memory serves me correctly, I think I have read other's complaints about the Crusoe elsewhere (regarding heat and power usage).
Other small items make the UX90 ideal for tinkerers: it accepts USB drives (even thumb drives) as bootable sources, the bluetooth performance is stellar (I was able to reach my phone through two semi-concrete), it has dual video cameras (one front and back - as more and more chat programs integrate video, I see this as a good item to have), and the overall performance of the processor is more than adequate. I also like the CF slot. I realize that it would have been nicer to have a PCMCIA or ExpressCard/34 slot, but I imagine that would have added too much unwanted bulk to the machine.
I am hoping with more R&D and/or experience, manufacturers like Sony will do a better job at making input easier (and this does not mean removing the input device). I have complained about devices that forego the keyboard altogether and I think this is a major mistake. Hand input is less likely to be as efficient as keyboard input - especially the smaller the screen gets. In the case of the UX90, I had Dynamism install Windows Tablet PC 2005. Although I think Windows Tablet PC has come a long way, the problem with it on the UX is that the screen is simply too small to make use of pen input (in written form). Having the keyboard is necessary.
So, in the end, I am happy with the device. Sony has done a great job at developing a small, powerful computing machine. Hopefully with time, refinements will make it even better.
* (I've mentioned this before, but I'll mention it again - I had a semi-disaster on a trip many, many years ago where my laptop went out completely and I had work that needed to be done. I ended up wasting more time and money on trying to get access to the internet and find a machine from which I could do the work needed - only three hours was needed - and regretted the whole ordeal. Ever since then, I've carried an extra laptop with me - usually as small as possible.)
