It seems the future of Lenovo netbooks is up in the air, as the company has stopped selling S-series laptops through its online store. The store currently lists all netbooks as "temporarily sold out — more stock is expected," however, Lenovo told us (and PCWorld) it has no plans to continue online sales of its existing S-series lineup. The move comes just a few months after the company showed off a few new netbooks, first by teasing its IdeaPad S110 and then announcing the S200 and S206 at CES. Lenovo did confirm to us that the S200 and S206 will be coming to market in June as planned, but noted that it's evaluating how and where they will be sold. So it seems we're in a dry spell for Lenovo netbooks, and the company's uncertainty probably isn't helping the flagging category. Dell got out of the netbook game last year, Acer's bottom line took a hit due to dwindling netbook interest, and tablets have taken over the low-cost portable computing space. Coupled with the rise of ultrabooks, we wouldn't be surprised if this is the first step in Lenovo getting out of the underpowered, undersized laptop market.
