[Asus  Eee Pad Transformer Prime] demandarin:
you already pointed out most main differences. I see some that might not be correct though.

last time I checked official spec of 300 on Asus page, it has a top speed of only 1.2Ghz. prime top speed is 1.4Ghz. both in stock configuration. 300 will eventually get developer support and roms and be clocked higher. bit never will be as powerful as the prime. they probably using a cheaper tegra3 or one not able to withstand the stresses prime tegra3 can handle. lower power silicon process probably. anyways, 1.2Ghz is still good.

300 is a lower end model. so you should expect it to be lower spec and not as powerful or as many features. for ex. prime Super IPS+ display vs. regular ips. that is a huge difference as far as brightness and clarity of tablet goes. with that said, 300 display should still look good being ips.

300 model won't have as good battery life as prime but will still be good enough for most.

300 is priced tl be more affordable. its mainly for those not able to afford a prime or have that much extra money to spare. which nothing is wrong with thst. its Asus version of economy tablet at the moment.

300 will be alot thicker and heavier than the prime. but its still thinner and lighter than the OG transformer its replacing. plus it'll come in cool assortment of different colors. that white looks so sexy and professional looking. its something about white colored electronics. cars, etc...that give it a more distinguished look to it.

300 does have a good thing going for it. its said to include ddr3 ram. so that will help alot with multitasking although less powerful than prime.

300 will be made out of plastic. This "SHOULD" help out with its wireless capabilities. BUT and I mean BUT we have already seen the FCC report on this device. its already stated wifi/BT on the same chip. the report also "SPECIFICALLY" notes that the wifi/BT working at the same time is really not possible or will interfere with each other. So simultaneous mode is not needed. we have a thread with links to FCC report on the 300 If you want confirmation. it also shows wifi antennae gain is lower than prime. this usually means its wifi is not as powerful and show worse performance. MAIN THING IS DONT EXPECT WIFI/BT PERFORMANCE TO BE BETTER THAN PRIMES. maybe the 300 model doesn't need wifi signal as strong as prime since it has plastic back. who knows. but I'm pretty sure it will still perform just fine on wireless capabilities. Any device with wifi/BT on same chip sharing same antennae is prone to issues when used simultaneously. As we have people who own other devices and experience the same thing on it. the only difference is manufacturers do the best they can to minimize the impact. but the impact is always there. whether large or minute. Manufacturers have been using this single chip design because it cuts down on costs. So Asus not really to blame on that. they can only do the best they can to minimize the interference with each other. they use this to save space also in the device. devices that have separate wifi and BT chips doesn't suffer as much or at all vs. angle chip design. so wifi/BT dropout issues is not a prime exclusive problem or issue. this goes for most electronics now that use single chip design.

also forgot to add the 300 has lesser quality/less MP having cans. I think its rear is only 5mp vs. prime 8mp. plus 300 doesn't have a flash at all. so no nighttime pics or video recording. or low light ones.

What this all boils down to is how much do you want to spend? how much can you afford to use on a ttablet? there is no real comparing to the prime because prime is superior across the board. which is why it commands the higher price tag. So if you trying to decide based on specs comparison of which is better, it'll always be the prime, as its superior. Prime is the premium model. 300 is the lowend/economy one. 300 is a great value in its own. it should still perform great. of you have an extra $100 to spend and want the best, Prime is it.

Don't let anyone influence WHAT YOU WANT. DECIDE FOR YOURSELF BASED ON THE BEST RESEARCH YOU HAVE ON BOTH. ASK YOURSELF DO I WANT THE MOST POWERFUL DEVICE AND BELLS N WHISTLES, OR CAN I BE SATISFIED WITH A LESS SPEC DEVICE WHICH IS GOOD IN ITS OWN RIGHT AND I SAVE $100? EITHER WAY YOU GO, IT'LL BE A GOOD CHOICE.

GOOD LUCK DECIDING.
