Edit: Take this all with a grain of salt. I figured out the workaround for my wifi issues just after posting. According to a Google support thread, ChromeOS (and/or the underlying *nix kernel) has issues with WPA+TKIP. I switched my router from WPA+TKIP to WPA+AES and watched as the Cr-48 changed instantly from a slow, laggy brick into a quick, snappy beast. This, I suppose, points out another problem: the lack of documentation. I read through the "known issues" page of the bug tracker and didn't see anything like this. It is likely that I may be blind and/or incompetent, though, so I'd be happy to be proved wrong here.
The biggest blow to my enthusiasm came from Google Talk which, after tempting me to try out video chat, proceeded to crash and refuse to connect. Actually, the notebook has been consistently slow with its network connection, leading nearly everything to have trouble. It's been taking upwards of five minutes to load simple webpages like reddit's front page, and more complex things like Gmail and Google Voice have been downright unusable because of the lag. It took more than 2 minutes to post a comment on a Facebook status. To make matters worse, the whole system seems to lock up when pages are loading, which means I can't even work with the things I have open. Even now, Blogger is having issues connecting to save this post. It's not constant, but there are enough issues to give me pause.
The fact that ChromeOS is struggling at doing tasks for which it was expressly designed, namely loading web pages and chatting, is both frustrating and a cause for great concern. The user experience crashes and burns quite often, with multitouch gestures simply not working and clicks being completely ignored. Seeming at random, two-finger scrolling with abruptly stop working. Clicks are apparently queued up, because clicking multiple times on a nonresponsive page yields a flurry of tabs opening once the page starts responding again.
I have been trying to load speedtest.net since I started typing this. It still has not finished. A page of comments on reddit required three refreshes before it loaded correctly. Google Talk still refuses to connect. Tweetdeck's Chrome app is incredibly slow and takes upwards of five minutes to load completely - that is, if it decides to load at all.
I've checked my network. Other wifi devices are just fine. My desktop, using a wired connection, load all of these pages just fine. It's not the connection. Maybe there is something screwy with the Cr-48's network stack or drivers. I find it hard to believe that I'm bumping into hardware limitations: a single-core Atom N455 with 2GB of RAM should not be choking on a few tabs of Chrome. I hope, however, that the performance troubles are all in software and that they can be fixed soon. ChromeOS is in no way marketable in its current form.
It isn't all bad, though. The hardware has continued to impress me, especially with battery life: this morning, upon unplugging the charger, I was showing a bit over 7:30 of battery life - an incredible figure for such a small battery, but after using the Cr-48 for the day (from noon to midnight) on and off, I was throughly impressed with its stamina. One of the most impressive things about ChromeOS is the speed with which it wakes from sleeping. It usually takes me longer to open the notebok and place my hands on the keyboard than it takes for the system to resume. Even rebooting takes less than 30 seconds from on-to-off-to-on again. It is most impressive.
In non-ChromeOS news, I finally broke down and picked up a PS3 Slim today after lusting after one for years now. I played GT5 and LittleBigPlanet for most of the day, marveling at the glorious graphics. Having a housemate, I thought it wise to pick up a second controller and also ended up getting the Blu-ray remote since I do so despise my noisy $20 DVD player. I'm never going to finish New Vegas at this rate.
Speedtest.net still hasn't loaded.
