Acer has unveiled a whole host of laptops at CeBIT 2010 - a technology tradeshow in Hannover, Germany. There's the Acer Aspire 8942, Acer Aspire 5942, Acer TravelMate 6594, Acer TravelMate 7740, Acer TravelMate 5740, and the Acer TravelMate 8x72. Almost all of them are slightly-updated versions of old models with an Intel Core i3, i5 or i7 processor inside.

We'll start at the top. The Aspire 8942 and 5942 are large desktop-replacement machines that come in 18.4- and 15.6-inch screen sizes. The larger offers a full HD 1920 x 1080 resolution, and the smaller comes in 1366 x 768. Both have Intel Core processors, and integrated TV tuners, Blu-ray disc drives and a multi-touch, gesture-recognising trackpad. They come with upto 8GB of memory, and upto 2 x 640GB of hard disk space.

Then there's the slightly more-mobile TravelMate 8x72 timeline series, which comes in 13.3-, 14-, and 15.6-inch screen sizes. They have Intel Core i3, i5 and i7 processors available, as well as energy saving LCD displays that promise more than 8 hours of battery life on one charge. The lightest model weighs just 1.6kg, and the machines come with upto 640GB of HDD or 160GB of SSD.

Moving on down the list, the Acer TravelMate 6594 has the choice of Intel Core i7 and i5 processors, and there's also the option of discrete graphics in the form of the ATI Radeon HD 5670. The screen size is 15.6 inches, with a 16:9 aspect ratio, and there's upto 8GB of DDR3 RAM and a "spacious" hard drive. There's an optical drive that can be swapped out for a second hard disk or extended battery. Without, the machine should manage upto 5 hours of battery life.

Lastly, there's the Acer TravelMate 7740 and 5740. These contain Intel Core i5 or i3 processors, upto 8GB of DDR3 RAM, and the option of either integrated graphics or the ATI Radeon HD5470. The difference between the two models is screen size - 17.3-inch in the 7740 and 15.6-inch in the 5740. There's a 16:9 aspect ratio, and a high-brightness LED backlit panel. 5 hours of battery life is promised.

Unfortunately, we don't have any pricing details for Britain - and with the exception of the 5942 and 8942 which are available now, all other products will be unavailable in the UK until at least mid May. When we hear more about Acer's plans on that front, we'll let you know.
