Batteries Suck

Yeah, I've learned to hate those new fangled Li-Ion batteries coz they're not really that good (IMHO). Especially because their disadvantages are not widely known/advertised ,this basically leads to you having to replace your Li-Ion batteries in 2-3 years for peak performance. Like how I had to replace my 3G iPod battery last month coz the charge was lasting 2-3 hours instead of 6-8 hours!!
At least I didn't have to pay $100 for apple to fix it, just £15 from Maplin (the plastic tools were shit tho and broke little bits of plastic into my iPod, I ended up using a flat head screwdriver).

Li-Ion
