So much FAIL in so little time. How can it be so laggy? It looks laggier than N8, which has a slower processor.

One reason that comes to mind is that Nokia saved on the BOM by not including the external Broadcom GPU so everything is rendered using the CPU only. The CPU is probably the same ARM11 that is used in all S^3 phones only overclocked to 1GHz.

If this is the case, then even the N900 is more powerful than this phone.
