Someone at Acer US should check their calendar, because while the company's TimelineX notebooks aren't expected to make their official debut until March 22nd, they've already shown up on the company's site. As expected, along with the 11.6-inch TimelineX 1830T from yesterday, there's also a 13.3-inch TimelineX 3820T, 14-inch TimelineX 4820T and a 15.6-inch TimelineX 5820T.
Update: Looks like whoever is responsible for the site has spotted the error - the new machines have been taken down.
The 1830T packs Intel Centrino or Core 2 Solo CPUs, but the rest get their pick from Intel's Calpella Core i3, i5 and i7 ranges. The Intel Core i3-330M and i3-350M (2.12GHz or 2.26GHz), Core i5-430M, i5-520M and i5-540M (2.26GHz, 2.40GHz or 2.53GHz) and Core i7-620M (2.66GHz) are all on offer, together with up to 8GB of memory and up to 640GB of storage.
There are also various ATI Mobility Radeon graphics options, including the HD 5470 and HD 5650, while wireless connectivity includes a choice of WiFi b/g or WiFi b/g/n, optional 3G and optional Bluetooth 2.1+EDR. Acer reckon you'll see up to 12hrs battery life from the 3820T, 4820T and 5820T, while the 1830T will get you up to 8hrs. No official pricing or launch dates, but going by Taiwanese rumors they'll be arriving there at the end of the month.
