Another reason to go ahead and upgrade to MCU2 is they may continue increasing the price. I upgraded even though my MCU1 was working fine. The higher resolution screens, snappier navigation, plus a functioning browser and voice controls made the $1700ish price tag more than worth it. I used a credit card promotion to pay for a good portion of the upgrade. One of those spend $2k in the first 3 months to get $750 cash back. If you have a high credit score and can take the couple point hit it's a good way to offset some of the cost.
