We had a chance to sit down with the new model for a few minutes recently, and we'll say it on no uncertain terms: this is by far the best Sidekick that Sharp (or Motorola, if you want to get technical about it) has ever made. It's the first model we've ever come across that actually feels professional and aspirational; it makes every other Sidekick seem like a toy by comparison in terms of physical design, materials, and build quality, and the addition of ActiveSync support makes this an entirely reasonable choice for young, white-collar types who cut their teeth on an older model. T-Mobile couldn't have picked a better time to be launching a device with tight Twitter integration, and it worked like a champ for us. We didn't have a ton of time to play with Microsoft Live Search and its GPS mapping capabilities, but maps loaded reasonably quickly, you've got live traffic data available to you, and naturally, you've got some pretty comprehensive search capabilities in there as well. The phone is physically large, but not impractically so -- owners of the original LX will feel right at home -- and the soft-touch plastic looks and feels great in either color. The 854 x 480 display is one of the best (if not the best) we've ever seen on a mobile device launched in the US, crisp to the point where individual pixels are utterly imperceptible to the naked eye (see the gallery shots to get a sense of what we mean). Put simply, from our brief time with it, we're struggling to come up with bad things to say -- and frankly, we're a little jealous of anyone plunking down the cash.
