I am very hessitant whether to buy ir not an iMac. A 2011model is expected, specially after seeing the new macbooksp with thunderbolt, but because of lion I am afraid that they might not be released until the summer and thats too long to wait. So, what do you guys think? Should Iwait or should I go? Idont see any convincing rumors or facts that point to an inmediate upgrade. Thanks in advance for sharing your thoughts.
