Hello, I'm a civil engineering student and I've been pinning over the sp3 for quite a while now, currently I have a $1000 to spend on a new laptop and thought since Microsoft knocked off $100 on the 128/i5 model I could jump and buy it now, but I won't have enough money to get the type cover or Microsoft Extended. Any suggestions for my predicament? I really wanted it just because I could write with the pen and run just about anything that I would need, but now I'm not so sure about waiting more, is Microsoft extended really worth it? Will waiting til they announce the sp4 be worthwhile in case the price gets lowered more?
