Katanya, dia telah upgrade beberapa MBA 11 inch dari Maverick ke Yosemite dan tiada sebarang masalah performance. Katanya lagi, upgrade Mac OS bukan seperti upgrade Android, jika berlaku sebarang masalah connection, proses upgrade Mac OS hanya akan PAUSE sahaja, dan akan resume setelah adanya kembali connection. Berbeza dengan Android, jika berlaku sebarang masalah dengan connection ketika proses upgrade, maka Android tidak boleh dibuka. Terpaksa lah factory reset.
Setakat ini, bersama MBA, paling ketara ialah kelajuan OS nya dan juga yang pasti adalah rekabentuk yang ringan dan nipis serta kecil memudahkan dibawa dan digunakan dimana-mana sahaja.
Masih belum berkesempatan menggunakan application-application di dalam MBA kerana kekurangan waktu.
Cuma yang pasti untuk blogging masih selesa guna Desktop PC mungkin kerana skrin besar, kedudukan keyboard pun selesa, antara penyebab saya dalam proses mendapatkan satu Desktop PC yang powerful untuk kerja-kerja di rumah.
Dibawah merupakan spesifikasi MBA yang saya beli, cukup sekadar browsing dan kerja-kerja yang saya perlu selesaikan.
