I started with a sp3 i5 128 and then upgraded to an i5 256 because I liked it so much. I don't know if I am just used to Apple quality and expecting the sp3 to be up to a comparable level. First the cameras are terrible, but I can live with that because most laptops don't have a rear camera anyway. Then I discover the back camera quit all together. Next I love the pen but sometimes it writes before touching the screen or doesn't write at all. Last week I discover wear marks under the hinge on a one week old unit, ok I can live with that too. Today I happen to notice the top of the unit is curved and with the slightest pressure it will straighten out, now I am worried about the sp3's durability. I take this unit with me everyday. I looked at a could of demo units at Best Buy and they are also curved at the top. Things I do like about the sp3. 1 Win 8.1 is great - I can still say this after being on a Mac for the last 6 years 2 touchscreen - Apple kinda lost me here 3 great high resolution screen 4 Handwriting !!!!! 5 Onenote 6 Backlit touch cover and highly improved touchpad 7 Great portable size and weight 8 Battery seems to be fine - not as long lasting as an MB Air but enough 9 Makes me forget my iPad - except when I am away from wifi - I have the original ATT unlimited plan 10 Speakers are great Well you guys understand. Its a device to love and hate! Maybe i'll just get a i3 64 for $650 (oh yeah add $130 for the type cover) and wait out the sp4 or ? Right now a i5 256 at $1150 + $130 just seems to too high priced for these issues.
