Going completely off-topic here, but yeah:
A calculator is needed in my math class! To trace graphics, solve huge formulas etc. It's really impossible to do this(and I classify myself not as dumb) without a calculator. Mine got stolen(grrrrrr!), and new a calculator like that costs €80. But my dad said to me he could try to do some insurance magic, so I'll see. Going on-topic(much needed
Moto G is indeed a beast for it's price(Google, I see what you did there), but it lacks an external sd! I know, I know, most of todays smartphones lack this, but it's a real bummer for me. I love music! I really do, and I know you don't need to have 1500 songs on your phone(yeah...), but I simply love it! Plus, when you already have purchased one of 32 GB, it's just dumb to not use it! Mine is stuffed with songs, some family guy episodes(yeah, I know...), pictures. And a buttload of themes/iconpacks. I just want to have a personal library!.
This is why I loved my S2. It was fast, could do anything, and had external sd support. I also think the S2 looks better than the S3, S4. With those phones you see immediately it's plastic crap. The S2 was plastic, but you couldn't really notice it(mine was black!). I'm really pissed mine got broken.
Ok, now the Nexus 5. I'm pretty sure that's going to be my new phone. I love the design, everything. And apparently the update to 4.4.2 extended the battery life(my only doubt), so you can easily use it a day(I'm a hardcore user, and have my screen on for 6/7 hours).
Now really on-topic(the subject was lag, not new phones):
I have to say my little E still got some power left. Using XboosT rom, Greenify, Link2SD, a few scripts(no OC for me, have some bad experience with that) I can live another few months with this phone.
I'm not trying to play the rich kid here, but I bought my S2 from my own money, and it was always blazing fast. So I didn't know what lag was, until I bought my E...
Anyway, have a nice day!
