MSI is apparently releasing a new MSI Wind U100 netbook with a 160GB HDD instead of the 80GB HDD available in the currently sold models.
Apparently Microsoft lifted the HDD storage limit on the low-cost XP license to 160GB.
MSI already offers also some 120GB MSI Wind models on their shop. Other features are the same, only the hard-drive sizes vary.
MSI should start to offer also SSD based MSI Wind U100 to directly compete with more of the Asus Eee PC netbooks.
