ASUS have just launched three devices under the Chi brand. The 12.5-inch T300, 10.1-inch T100 and the 8.9-inch T90.

We’ve seen the T300 Chi before through an accidental hands-on. It will launch with a Full HD display, Core M CPU and 128GB SSD for $699 in February. The ASUS T100 Chi is an Atom-based 2-in-1 much the same as the T100 that already exists. A Full HD screen, a year of Office 365, 2GB RAM and 64GB storage will cost you $399. Finally the T90 Chi is an 8.9-inch tablet and bluetooth keyboard with 1280×768 screen, Intel Atom CPU and a year of Office 365 will start at $299. A 64GB SSD option is available on the T90 Chi.

ASUS Press release here. (We’re updating information below as we get it…)

The Transformer Book T90 is the one that will interest many readers here.

The ASUS T100 Chi looks just as sweet though. Total weight is 1.06 KG and the price is just $100 more. People are going to have a hard time deciding between the T90 and T100.

Pricing for the T300 looks good if you’re not interested in a WQHD screen as long as the SSD is a real one. It’s listed as an iSSD on the ASUS website which could mean ‘integrated’ (which would mean eMMC.) We’ll have to wait for details on that. Here are the official specs we have so far for the T300 Chi.
