Acer's plan to become more like Apple has hit a little speed bump. Rather than sell a record amount of tablets, the company slashed its tablet shipment target for 2011 by nearly 60 percent.

Reuters reports that Acer also lowered its notebook shipment outlook.

The forecasts might be an indication of Acer realigning its outlook with reality. The company missed its last three quarterly forecasts while under the leadership of CEO Gianfranco Lanci. Lanci resigned in March over a difference in vision with the board of directors over the company's future. 

According to Reuters, Acer Chairman J.T. Wang told said Q3 will be considerably more stable than the first half of the year, and that "the fourth quarter will be even better." Still, the new target for tablet shipments is 2.5-3 million units by years end, instead of the 5-7 million the company had envisioned at the start of the year. 

The turmoil within the company and the missed forecasts have adversely affected Acer's shares. According to Reuters, shares have plummeted 30 percent since the company first cut its PC revenue outlook on March 25. In May, Acer posted a drop in total sales of nearly 30 percent.

While Acer said it expected to sell 800,000 tablets in each of the second and third quarters of the year, Apple, by comparison, sold 4.69 million units in Q2 alone.

If Acer wants to become more like Apple, it's going to have to seriously step up its game.
