Acer will refresh its Timeline thin-and-light series in a few weeks with several new CPUs. We don't have any exact launch dates, but the refresh will probably coincide with the Windows 7 launch in late October.

Starting at the low end, Acer will offer Celeron-based Timelines. So far we came across the 5410T and 3410T, 15.6- and 13.3-inch models based on the Celeron 723 at 1.3GHz. The good thing is that they are dirt cheap and that they are already shipping in some markets. The 13-incher to sell under €500, and the 15-inch version shouldn't be much pricier either.

The addition of dual-core SU4100 and SU7300 parts is a bit more interesting. The former runs at 1.3GHz and has 2MB of L2 cache and it should nicely fill the gap between the SU3500 and SU9400, and the best part of the story is its affordable price. According to some early listings in Britain, the SU4100-based 3810T will sell for 529 quid, which is about the same as you would pay for a SU3500-based version.

As for the SU7300-based models, we didn't manage to find as many listings, and the prices were a bit odd, i.e. too high to sound realistic. However, it still seems you will be able to get a SU7300 for less than a SU9400-based model, under £600. The SU7300 is also clocked at 1.3GHz, but has 3MB of L2 cache.

Obviously, you can expect the new chips to appear in other Timeline series models, and their Travelmate siblings. Just watch for the 'Z' suffix at the end of the designation.
